GENERAL

We are principally engaged in the manufacturing and selling of pulp-based products. We manufacture quality consumer tissue, away-from-home tissue, parent roll tissue, machine-glazed tissue, bleached paperboard, pulp and wood products at 15 manufacturing locations in the U.S. and Canada. Our private label tissue products, such as facial and bath tissue, paper towels and napkins, are used primarily at-home and are principally sold to major retailers and wholesale distributors, which include grocery, drug, mass merchants and discount stores. Our paperboard is sold primarily in the high-end segment of the packaging industry and is ultimately used by our customers to make packaging for products ranging from liquids to pharmaceuticals to consumer goods packaging, all of which demand high quality construction and print surfaces for graphics. We also manufacture wood products, including quality cedar used for its attractive appearance, and lumber products for construction.

On December 27, 2010, we acquired Cellu Tissue Holdings, Inc., or Cellu Tissue, and consolidated the acquisition in our financial statements as of that date. The financial position and results of Cellu Tissue’s operations and cash flows are fully reflected in these condensed consolidated financial statements relating to periods subsequent to the acquisition date.

FINANCIAL STATEMENT PREPARATION AND PRESENTATION

The accompanying Condensed Consolidated Balance Sheets at June 30, 2011 and December 31, 2010, and the related Condensed Consolidated Statements of Operations, Cash Flows, and Comprehensive Income for the three months and six months ended June 30, 2011 and 2010 have been prepared in conformity with accounting principles generally accepted in the United States of America, or GAAP. We believe that all adjustments necessary for a fair statement of the results of the interim periods presented have been included. The results of operations for any interim period are not necessarily indicative of the results of operations to be expected for the full year.

This Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2010, as filed with the Securities and Exchange Commission, or SEC, on March 11, 2011.

We evaluated all subsequent events through the date these financial statements were filed with the SEC.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ESTIMATES

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Significant areas requiring the use of estimates and measurement of uncertainty include the determination of net realizable value for deferred tax assets, environmental matters, goodwill and intangible assets, uncertain tax positions and pension and postretirement obligation assumptions. Actual results could differ from those estimates and assumptions.

TRADE ACCOUNTS RECEIVABLE

As of June 30, 2011 and December 31, 2010, we had allowances of $1.5 million and $1.0 million, respectively, for doubtful accounts based on our estimates of the collectability of outstanding receivables.

INVENTORIES

Inventories are stated at the lower of current average cost or market, except that the last-in, first-out method is used to determine cost of logs, chips, sawdust and the majority of our lumber. An average cost method is used to determine the cost of all other inventories.

Table of Contents

PROPERTIES

Property, plant and equipment are stated at cost, including any interest costs capitalized, less accumulated depreciation. Depreciation of buildings, equipment and other depreciable assets is determined using the straight-line method. Assets we acquire through business combinations have estimated lives that are typically shorter than the assets we construct or buy new. Accumulated depreciation totaled $1,323.7 million and $1,290.1 million at June 30, 2011 and December 31, 2010, respectively.

For the three months and six months ended June 30, 2011, we capitalized $1.0 million and $1.5 million, respectively, of interest expense associated with the construction of our new tissue manufacturing and converting facilities in Shelby, North Carolina.

EMPLOYEES

Unions represent hourly employees at seven of our manufacturing sites. There are no hourly union labor contracts expiring in 2011. The union contracts that had expired as set forth on page 9 of our Annual Report on Form 10-K for the year ended December 31, 2010 were all ratified during the second quarter of 2011.

In June 2011, accounting guidance was issued related to Other Comprehensive Income, or OCI. The guidance eliminates the option to present the components of OCI as part of the statement of changes in stockholders’ equity, and instead requires consecutive presentation of the statements of net income and OCI either in a continuous statement of comprehensive income or in two separate but consecutive statements. The guidance is effective for interim and annual periods beginning after December 15, 2011, with earlier adoption permitted, and adoption will not impact the accounting for OCI, only its presentation in our consolidated financial statements.

In December 2010, accounting guidance was issued that modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist such as if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. This guidance became effective for us on January 1, 2011 and has not had an impact on our consolidated financial statements.

Inventories at the balance sheet dates consist of:

Intangible assets at the balance sheet dates are comprised of the following:

Pursuant to authoritative guidance, we use our estimated annual effective tax rate to allocate expected annual income tax expense to interim periods. The rate is the ratio of estimated annual income tax expense to estimated pre-tax ordinary income, and excludes what we refer to as “discrete items,” which are significant, unusual or infrequent items reported separately net of their related tax effect. The estimated annual effective tax rate is applied to the current interim period’s ordinary income to determine the income tax expense allocated to the interim period. The income tax effects of discrete items are then determined separately and recognized in the interim period in which the income or expense items arise.

Our estimated annual effective tax rate for 2011 is 35.2%, compared with 34.8% at June 30, 2010. We recorded income tax expense of $8.6 million and $14.8 million, respectively in the three and six months ended June 30, 2011, compared to $12.6 million and $18.4 million, respectively, in the three and six months ended June 30, 2010. The actual rates for the three and six months ended June 30, 2011 were 38.3% and 43.1%, respectively, compared to rates of 38.0% and 46.7% for the three and six months ended June 30, 2010, respectively. As discussed below, the higher rates for the six month periods resulted from the net impact of reporting discrete items of approximately $2.7 million of net expense in the six months ended June 30, 2011 period, and $4.7 million of net expense in the six months ended June 30, 2010.

The effective tax rate for the six months ended June 30, 2011 was primarily impacted by three main discrete items. The first was an increase in tax expense based on evaluating our state tax structure as Cellu Tissue is integrated with the Company’s operations. The second discrete item was a decrease in tax expense associated with certain transaction costs relating to the Cellu Tissue acquisition that were determined to be deductible under the Internal Revenue Code. The final discrete item was an increase to tax expense relating to interest accrued on uncertain tax positions for the period. The higher tax rate for the six months ended June 30, 2010 was primarily due to the passage of the Patient Protection and Affordable Care Act on March 23, 2010, which required us to reverse $4.4 million of deferred tax assets during the period ended March 31, 2010 relating to the elimination of an income tax deduction for prescription drug benefits provided to retirees and reimbursed under the Medicare Part D retiree drug subsidy beginning in January 2013, for which there is no comparable impact in 2011.

We are eligible to convert gallons previously claimed under the Alternative Fuel Mixture Tax Credit, or AFMTC, to the Cellulosic Biofuel Producer Credit, or CBPC; however, due to CBPC carryovers from 2010, we do not anticipate converting additional gallons from AFMTC to CBPC during 2011. We have the ability to convert additional gallons to CBPC until the end of 2013.

$375 MILLION SENIOR NOTES DUE 2018

On October 22, 2010, we sold $375.0 million aggregate principal amount of senior notes, which we refer to as the 2010 Notes. The 2010 Notes mature on November 1, 2018, have an interest rate of 7.125% and were issued at their face value. The issuance of these notes generated net proceeds of $367.5 million after deducting offering expenses. The net proceeds from the issuance of the 2010 Notes were used to finance in part our acquisition of Cellu Tissue, to refinance certain existing indebtedness of Cellu Tissue, and to pay fees and expenses incurred as part of the 2010 Note offering, acquisition of Cellu Tissue and related transactions.

The 2010 Notes are guaranteed by Cellu Tissue and certain of our other existing and future direct and indirect domestic subsidiaries. The 2010 Notes are equal in right of payment with all other existing and future unsecured senior indebtedness and are senior in right of payment to any future subordinated indebtedness. The 2010 Notes are effectively subordinated to all of our existing and future secured indebtedness, including borrowings under our secured revolving credit facility, which is secured by certain of our accounts receivable, inventory and cash. The terms of the 2010 Notes limit our ability and the ability of any restricted subsidiaries to borrow money; pay dividends; redeem or repurchase capital stock; make investments; sell assets; create restrictions on the payment of dividends or other amounts to us from any restricted subsidiaries; enter into transactions with affiliates; enter into sale and lease back transactions; create liens; and consolidate, merge or sell all or substantially all of our assets.

In connection with the issuance of the 2010 Notes, we entered into a registration rights agreement with the initial purchaser of the 2010 Notes. Pursuant to the registration rights agreement, we filed a registration statement on April 29, 2011 with the Securities Exchange Commission, or SEC, pursuant to which we exchanged the 2010 Notes on June 28, 2011, for notes with substantially similar terms that are registered under the Securities Act of 1933, as amended.

$150 MILLION SENIOR NOTES DUE 2016

In June 2009, we issued senior unsecured notes, which we refer to as the 2009 Notes, in aggregate principal amount of $150.0 million. The 2009 Notes are due on September 15, 2016 and have an interest rate of 10.625%. The 2009 Notes were issued at a price equal to 98.792% of their face value.

The 2009 Notes are general unsecured obligations and are therefore not secured by our assets and are effectively subordinated to all of our existing and future secured indebtedness, including borrowings under our secured revolving credit facility, which is secured by certain of our accounts receivable, inventory and cash. The terms of the 2009 Notes limit our ability and the ability of any restricted subsidiaries to borrow money; pay dividends; redeem or repurchase capital stock; make investments; sell assets; create restrictions on the payment of dividends or other amounts to us from any restricted subsidiaries; enter into transactions with affiliates; enter into sale and lease back transactions; create liens; and consolidate, merge or sell all or substantially all of our assets.

CITYFOREST INDUSTRIAL BONDS

In connection with our acquisition of Cellu Tissue, we assumed Variable Rate Demand Solid Waste Disposal Facility Revenue Bonds, Series 1998, or IRBs, previously issued by a subsidiary of Cellu Tissue. Approximately $15.2 million in aggregate principal face amount of the IRBs was outstanding at June 30, 2011. The IRBs have scheduled semi-annual payments of principal, with the balance payable at maturity on March 1, 2028. The variable interest rate on the IRBs was 2.28% as of June 30, 2011. The IRBs are guaranteed by Cellu Tissue and contain various customary covenants and events of default.

Cellu Tissue-CityForest LLC, or CityForest, a wholly-owned subsidiary of Cellu Tissue, is required, under the terms of the Indenture of Trust governing the IRBs, or CityForest Indenture, to provide a letter of credit in favor of the trustee. CityForest is a party to a Second Amended and Restated Reimbursement Agreement dated as of December 27, 2010, with Associated Bank pursuant to which Associated Bank provided a letter of credit to the trustee. The trustee is permitted to draw upon the letter of credit to pay principal and interest due on the IRBs, and to provide liquidity to purchase IRBs put to CityForest by bondholders and not remarketed; and CityForest is obligated under the Second Amended and Restated Reimbursement Agreement to reimburse Associated Bank for any such draws. The expiration date of the letter of credit is February 15, 2012. Under the terms of the Second Amended and Restated Reimbursement Agreement, CityForest is required, on or before September 30, 2011, to cause the letter of credit to be replaced with a substitute letter of credit from a third-party bank. CityForest’s failure to cause the letter of credit to be replaced by September 30, 2011 will constitute an event of default under the Second Amended and Restated Reimbursement Agreement.

The Second Amended and Restated Reimbursement Agreement contains various customary covenants applicable to CityForest, including a requirement to comply on a quarterly basis with a maximum leverage covenant and a minimum fixed charge coverage covenant based on CityForest’s balance sheet and statement of operations. The maximum permitted leverage ratio is 2.5 to 1.0. As of June 30, 2011, the leverage ratio was 1.3 to 1.0. The minimum permitted fixed charge coverage ratio is 1.2 to 1.0. As of June 30, 2011, the fixed charge coverage ratio was 4.6 to 1.0.

Clearwater Paper has guaranteed all of the obligations of CityForest under the Second Amended and Restated Reimbursement Agreement, pursuant to a Guaranty, dated as of December 27, 2010, executed in favor of Associated Bank.

The Second Amended and Restated Reimbursement Agreement provides that in certain circumstances where Cellu Tissue incurs indebtedness, as defined, in excess of amounts currently permitted under the CityForest Indenture or refinances the indebtedness issued under the CityForest Indenture, CityForest may be required to cause the bonds to be redeemed or provide a new letter of credit from another lender. As required by the Second Amended and Restated Reimbursement Agreement, we had $1.1 million of restricted cash as of June 30, 2011.

During the second quarter of 2011, we made the determination to redeem the outstanding balance of the IRBs and are initiating that process. As a result, the entire $15.2 million balance of the IRBs and the associated restricted cash are included in “Current portion of long-term debt” and “Restricted cash,” respectively, on our June 30, 2011 Condensed Consolidated Balance Sheet.

REVOLVING CREDIT FACILITY

On November 26, 2008, we entered into a four-year $125 million revolving credit facility with certain financial institutions. The amount available to us under the revolving credit facility is based on the lesser of 85% of our eligible accounts receivable plus approximately 65% of our eligible inventory, or $125 million.

As of June 30, 2011, there were no borrowings outstanding under the credit facility, but approximately $8.4 million of the credit facility was being used to support outstanding standby letters of credit. Loans under the credit facility bear interest at LIBOR plus between 2.25% and 2.75% for LIBOR loans, and a base rate effectively equal to the agent bank’s prime rate plus between 0.75% and 1.25% for other loans. The percentage margin on all loans is based on our fixed charge coverage ratio for the last fiscal quarter, which is recalculated on a quarterly basis. As of June 30, 2011, we would have been permitted to draw $116.6 million under the credit facility at LIBOR plus 2.75%.

Table of Contents

A minimum fixed charge coverage ratio is the only financial covenant requirement under our credit facility and is triggered when an event of default exists or when availability falls below 20%, at which time the minimum fixed charge coverage ratio must be at least 1.0 to 1.0. As of June 30, 2011, the fixed charge coverage ratio for the last twelve months was 1.2 to 1.0.

The following table details the components of net periodic cost of our pension and other postretirement employee benefit, or OPEB, plans for the periods presented:

As discussed in the notes to our consolidated financial statements in our 2010 Form 10-K, our company-sponsored pension plans were underfunded by $55.4 million at December 31, 2010. The funded status as of December 31, 2010 improved by $40.5 million over the funded status as of December 31, 2009 due to cash contributions made to the pension plans during 2010, positive returns on pension asset investments and plan changes resulting in the salaried pension plan being closed to new entrants commencing December 15, 2010 and frozen as to the accrual of further benefits effective December 31, 2011. As a result of being underfunded, we are required to make contributions to our qualified pension plans. During the six months ended June 30, 2011, we contributed $8.5 million to these pension plans. In July 2011, we contributed an additional $1.3 million. Our remaining required contributions for 2011 are expected to be approximately $2.7 million (plus interest).

During the six months ended June 30, 2011, we made approximately $0.1 million of contributions to our non-qualified pension plan, and we estimate contributions will total approximately $0.3 million in 2011. We do not anticipate funding our OPEB plans in 2011 except to pay benefit costs as incurred during the year by plan participants.

Earnings per common share are computed by dividing net earnings by the weighted average number of common shares outstanding in accordance with accounting guidance related to earnings per share. The following table reconciles the number of common shares used in calculating the basic and diluted net earnings per share:

We recognize equity-based compensation expense for all equity-based payment awards made to employees and directors, including restricted stock units and performance shares, based on estimated fair values.

Employee equity-based compensation expense was recognized as follows:

The following table summarizes the number of share-based awards granted under the Clearwater Paper Corporation 2008 Stock Incentive Plan during the six months ended June 30, 2011 and the average grant-date fair value of the awards:

DIRECTOR AWARDS

We recorded director equity-based compensation income totaling $0.7 million for the three months ended June 30, 2011, as a result of a lower stock price at the end of the period, and expense of $0.7 million for the three months ended June 30, 2010. We recorded director equity-based compensation expense totaling $0.2 million and $1.0 million for the six months ended June 30, 2011 and 2010, respectively.

The estimated fair values of our financial instruments at the dates presented below are as follows:

Accounting guidance establishes a framework for measuring the fair value of financial instruments, providing a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities, or “Level 1” measurements, and the lowest priority to unobservable inputs, or “Level 3” measurements.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used should seek to maximize the use of observable inputs and minimize the use of unobservable inputs.

We are organized in two reportable operating segments: Consumer Products and Pulp and Paperboard. Prior to January 1, 2011, intersegment pulp transfers from our Pulp and Paperboard segment to our Consumer Products segment were recorded as net sales for the Pulp and Paperboard segment at prevailing market prices and eliminated, on a consolidated basis, to reconcile the segments’ total net sales to our consolidated net sales. Commencing January 1, 2011, rather than recording the intersegment transfer of pulp through net sales, the costs of pulp are transferred from the Pulp and Paperboard segment to the Consumer Products segment. As a result, there are no eliminations required to reconcile our total consolidated net sales to the segments’ total net sales. In order to facilitate comparability with the 2010 period, the operating results for the three and six months ended June 30, 2010 have been recast to reflect the revised cost transfer methodology.
