Clearwater Paper Corporation
Notes to Consolidated Financial Statements
(Unaudited)
NOTE 1 BASIS OF PRESENTATION
The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, the consolidated financial position, results of operations, stockholders' equity and cash flows for us and our subsidiaries for the interim periods presented. Results of operations for interim periods are not necessarily indicative of results to be expected for an entire year. These consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020. All dollar amounts are shown in millions, except per share.
NOTE 2 RECENTLY ADOPTED AND NEW ACCOUNTING STANDARDS
Recently Adopted Accounting Standards
In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes, which removes certain exceptions, such as the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year, and simplifies the accounting for income taxes in areas such as franchise tax (or similar tax) that is partially based on income. The new standard is effective for annual and interim periods beginning after December 15, 2020. This ASU was adopted as of January 1, 2021 and did not have a material impact on our consolidated financial statements.
We reviewed all other new accounting pronouncements issued in the period and concluded that they are not applicable or not material to our business.
NOTE 3 FAIR VALUE MEASUREMENTS
Carrying amounts reported on the balance sheet for cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximate fair value due to the short-term maturity of these instruments.
The fair value of our debt is included in the following table:

| June 30, 2021 |  | December 31, 2020
Term loan maturing 2026, variable interest rate | $ | 129.1 |  |  | $ | 129.6 |
2014 Notes, maturing 2025, fixed interest rate | $ | 319.1 |  |  | $ | 325.1 |
2020 Notes, maturing 2028, fixed interest rate | $ | 275.0 |  |  | $ | 285.3 |

Fair Value of Nonfinancial Assets
We measure certain nonfinancial assets at fair value on a nonrecurring basis. These assets include inventory and property, plant and equipment that are written down to fair value when they are held for sale or determined to be impaired. During the second quarter of 2021, we announced the closure of our Neenah, Wisconsin tissue and converting operations and accordingly measured the inventory and property, plant and equipment at fair value on a nonrecurring basis based upon our expected proceeds from the related asset sales less applicable selling costs. This resulted in an impairment of $36.9 million in the second quarter of 2021.

Other accrued liabilities | 20.7 |  |  | 19.6 |
| $ | 254.1 |  |  | $ | 243.1 |

Included in accounts payable and accrued liabilities is $7.5 million and $12.1 million related to capital expenditures that had not yet been paid as of June 30, 2021 and December 31, 2020.
NOTE 7 INCOME TAXES
For interim periods, accounting standards require that income tax expense be determined by applying the estimated annual effective income tax rate to year-to-date results, unless this method does not result in a reliable estimate of year-to-date income tax expense. Each period, the income tax accrual is adjusted to the latest estimate and the difference from the previously accrued year-to-date balance is adjusted to the current quarter.
For the six months ended June 30, 2021, our income tax expense reflects an income tax benefit of $13.5 million as compared to an income tax provision of $4.2 million in the comparable period of 2020. Our effective tax rate for the first six months of 2021 of 25% varied from the U.S. statutory tax rate of 21% primarily due to the effects of state taxes and nondeductible compensation. Our effective tax rate for the first six months of 2020 varied from the statutory U.S. federal income tax rate of 21% primarily due to a $7.1 million benefit from the provisions of the Coronavirus Aid, Relief, and Economic Security Act.

NOTE 14 SEGMENT INFORMATION
We operate in two segments: Pulp and Paperboard and Consumer Products. Our business units have been aggregated into these two segments based upon the similarity of economic characteristics, customers and distribution methods. Our results of operations are summarized below for each of these segments separately. Segment information was prepared in accordance with the same accounting principles as those described in Note 1 of the Notes to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020. Certain amounts have been reclassified from the prior year presentation to reflect the realignment of Clearwater Paper’s baled pulp sales to record inter-segment sales at market price and the realignment of outside pulp sales to the producing segment.

ITEM 2. | Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the consolidated financial statements and Notes thereto included herein and our audited Consolidated Financial Statements and Notes thereto for the fiscal year ended December 31, 2020, as well as the information under the heading “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” that are part of our Annual Report on Form 10-K for the year ended December 31, 2020.
OVERVIEW
Executive Summary
We recorded a decrease of 15% in net sales to $406.4 million for the three months ended June 30, 2021 compared to $480.6 million for the three months ended June 30, 2020. We recorded net loss for the three months ended June 30, 2021 of $51.6 million, or $3.10 per diluted share, compared to net income of $22.8 million or $1.36 per diluted share in the three months ended June 30, 2020. We recorded Adjusted EBITDA for the three months ended June 30, 2021 of $14.8 million compared to $78.9 million in the three months ended June 30, 2020.
We recorded a decrease of 13% in net sales to $832.3 million for the six months ended June 30, 2021 compared to $958.5 million for the six months ended June 30, 2020. We recorded net loss for the six months ended June 30, 2021 of $39.6 million, or $2.37 per diluted share, compared to net income of $33.1 million or $1.99 per diluted share in the six months ended June 30, 2020. We recorded Adjusted EBITDA for the six months ended June 30, 2021 of $69.1 million compared to $134.3 million in the six months ended June 30, 2020.
Q2 2021 Announced Mill Closure
During the second quarter of 2021, we announced the closure of our Neenah, Wisconsin, tissue and converting operations. The Neenah Mill includes three tissue machines and ten tissue converting lines. The closure will reduce our total annual tissue and tissue converting production capacities by approximately 54,000 and 70,000 tons. As a result of the announced closure, we recorded $41.7 million of impairment and other closure costs. The primary components of the $41.7 million charge include an impairment to property plant and equipment of $31.6 million, a write-down to inventory of $5.3 million and $4.8 million of cash expenses for our employees including severance and WARN act related payments. In the third quarter, we expect $4.2 million of additional cash expenses for employee severance and WARN act related payments.
See discussion on segment level results regarding net sales, operating results and Adjusted EBITDA in “Our Operating Results” below.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
The preparation of financial statements in accordance with GAAP requires our management to select and apply accounting policies that best provide the framework to report our results of operations and financial position. The selection and application of those policies requires management to make difficult, subjective and complex judgments concerning reported amounts of revenue and expenses during the reporting period and the reported amounts of assets and liabilities at the date of the financial statements. As a result, it is possible that materially different amounts would be reported under different conditions or using different assumptions.
Impairment of Long-Lived Assets
We monitor our long-lived assets for impairment indicators on an ongoing basis in accordance with GAAP. If impairment indicators exist, we perform the required impairment analysis by comparing the undiscounted cash flows expected to be generated from the long-lived assets to the related net book values. If the net book value exceeds the undiscounted cash flows, an impairment loss is measured and recognized. An impairment loss is measured as the difference between the net book value and the fair value of the long-lived assets. Fair value is estimated based upon a combination of market and cost approaches, as appropriate.
Our impairment loss calculations contain uncertainties because they require management to make assumptions and to apply judgment to estimate future cash flows and asset fair values. We do not believe a material change in the estimates or assumptions that we use to calculate long-lived asset impairments is likely. However, if actual results are not consistent with our estimates and assumptions used in estimating future cash flows and asset fair values, we may be exposed to losses that could be material.
As of June 30, 2021, other than the item mentioned above, there have been no significant changes with regard to the critical accounting policies and estimates disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.
14

NON-GAAP MEASURES
In evaluating our business, we utilize several non-GAAP financial measures. A non-GAAP financial measure is generally defined by the SEC as one that purports to measure historical or future financial performance, financial position or cash flows, but excludes or includes amounts that would not be so excluded or included under applicable GAAP guidance. In this report on Form 10-Q, we disclose overall and segment earnings (loss) from operations before interest expense, net, non-operating pension and other postretirement benefit costs, taxes, depreciation and amortization, other operating charges, net, and Adjusted EBITDA which is a non-GAAP financial measure. Adjusted EBITDA is not a substitute for the GAAP measure of net income (loss) or for any other GAAP measures of operating performance.
We have included Adjusted EBITDA on a consolidated and segment basis in this report because we use them as important supplemental measures of our performance and believe that they are frequently used by securities analysts, investors and other interested persons in the evaluation of companies in our industry, some of which present Adjusted EBITDA when reporting their results. We also use Adjusted EBITDA to evaluate our performance as compared to other companies in our industry that have different financing and capital structures and/or tax rates. It should be noted that companies calculate Adjusted EBITDA differently and, therefore, our Adjusted EBITDA measures may not be comparable to Adjusted EBITDA reported by other companies. Our Adjusted EBITDA measures have material limitations as performance measures because they exclude interest expense, income tax (benefit) expense and depreciation and amortization which are necessary to operate our business or which we otherwise incur or experience in connection with the operation of our business. In addition, we exclude other income and expense items which are outside of our core operations.

Sales volumes decreased slightly in our Pulp and Paperboard segment for the three and six month periods ended June 30, 2021 compared to the same periods in the prior year due to lack of product availability due to the planned maintenance shutdown at our Lewiston facility during the second quarter, as well as the impacts on us from the North American winter and ice storm during the first quarter of 2021. Sales prices increased in our Pulp and Paperboard segment for the three and six month periods ended June 30, 2021 compared to the same periods in the prior year due to the impacts of our announced price increase and changes in product mix.
During the second quarter of 2021, we realized significant cost increases due to the planned major maintenance shutdown at our Lewiston location.
Overall, the decrease in operating income and Adjusted EBITDA for the three and six month periods ended June 30, 2021 as compared to the same periods in the prior year was driven by our planned maintenance shutdown which was partially offset by higher sales prices.

n.m. - not meaningful
Sales volumes decreased in our Consumer Products segment for the three and six month periods ended June 30, 2021 compared to the same periods in the prior year as consumer demand slowed due to the lessening impact of COVID-19. Additionally, customers and consumers began reducing inventory resulting in significantly lower demand in these periods as compared to the same periods in the prior year. Sales prices changed in our Consumer Products segment for the three and six month periods ended June 30, 2021 compared to the same periods in the prior year due primarily to changes in product mix. From a product perspective, in the second quarter and first six months of 2021 compared to the same periods in 2020, we saw the decreases across all product lines. As a percentage of our Consumer Products segment, paper towel and bath tissue represent more than 80% of our business. We saw minor increases in our non-retail business primarily related to an increase in the away from home business as COVID-19 impacts have subsided with parent rolls sales relatively flat between periods. Sales prices in this category decreased in the periods presented due to a higher percentage of away from home products as compared to parents rolls which is generally at a lower sales price per ton. As a result of the announced closure of our Neenah, Wisconsin operations, we will be exiting the away from home market.
Overall, the decrease in operating income and Adjusted EBITDA for the three and six month periods ended June 30, 2021 compared to the same periods in the prior year was driven by higher input costs, primarily pulp, reduced operations to balance supply and demand and lower sales volumes.
Corporate expenses
Corporate expenses for the three and six months ended June 30, 2021 were $15.0 million and $30.5 million compared to $17.6 million and $31.0 million in the same periods in the prior year. The reduction between periods is primarily related to the lower incentive compensation based upon lower operating results. Corporate expenses primarily consist of corporate overhead such as wages and benefits, professional fees, insurance and other expenses for corporate functions including certain executive officers, public company costs, information technology, financial services, environmental and safety, legal, supply management, human resources and other corporate functions not directly associated with the business operations.

Other operating charges
See Note 8 "Other operating charges" of the Notes to the Consolidated Financial Statements included in Item 1 of this report for additional information.
Interest expense
Interest expense for the three month period ended June 30, 2021 compared to the same period in the prior year was $2.7 million lower and for the six months ended June 30, 2021 compared to the same period in the prior year was $6.2 million lower due to lower debt outstanding. See Note 9 "Non-operating income (expense)" of the Notes to the Consolidated Financial Statements included in Item 1 of this report for additional information.
Potential impairments
We review from time to time possible dispositions or reorganization of various assets in light of current and anticipated economic and industry conditions, our strategic plan and other relevant factors. Because a determination to dispose or reorganize particular assets may require management to make assumptions regarding the transaction structure of the disposition or reorganization and to estimate the net sales proceeds, which may be less than previous estimates of undiscounted future net cash flows, we may be required to record impairment charges in connection with decisions to dispose of assets.

LIQUIDITY AND CAPITAL RESOURCES
Our principal sources of liquidity are existing cash balances, cash generated by our operations and our ability to borrow under such credit facilities as we may have in effect from time to time. Our principal uses of liquidity are paying the costs and expenses associated with our operations, servicing outstanding indebtedness and making capital expenditures. We may also from time to time prepay or repurchase outstanding indebtedness (including by issuing new indebtedness subject to market conditions to refinance such outstanding indebtedness) or acquire assets or businesses that are complementary to our operations.
Operating Activities
Net cash flows provided by operating activities for the six months ended June 30, 2021 were $48.1 million compared to $120.4 million in the first six months of 2020. This decrease was driven by lower net income. Accounts receivable and accounts payable agings have remained relatively consistent with balances as of December 31, 2020.
Investing Activities
During the six months ended June 30, 2021, net cash flows used in investing activities were $21.1 million compared to $17.8 million in the prior year period. Included in "Accounts payable and accrued liabilities" on our Consolidated Balance Sheets was $7.5 million and $8.5 million related to capital expenditures that had not yet been paid at June 30, 2021 and 2020.
Throughout 2021, we expect cash paid for capital expenditures to be approximately $50 million to $55 million.
Financing Activities
Net cash flows used by financing activities were $2.0 million for the six months ended June 30, 2021 a s compared to $75.8 million for the same period of 2020. The change was driven by the absence of debt repayment in the six months ended June 30, 2021 as compared to the corresponding period of 2020.
Credit Agreements
ABL Credit Agreement
The ABL Credit agreement matures on July 26, 2024 and includes a $250 million revolving loan commitment, subject to borrowing base limitations based on a percentage of applicable eligible receivables and eligible inventory. Based upon our Consolidated Balance Sheet as of June 30, 2021, our borrowings supported up to $239.2 million of availability under the line, of which no borrowings were outstanding and $3.6 million was utilized to issue letters of credit. We may, at our option, prepay any borrowings under the ABL Credit Agreement, in whole or in part, at any time and from time to time without premium or penalty (except in certain circumstances).
The ABL Credit Agreement also contains a financial covenant, which requires us to maintain a consolidated fixed charge coverage ratio of not less than 1.10 to 1.00, provided that the financial covenant under the ABL Credit Agreement is only applicable when unused availability falls below $25 million. As of June 30, 2021, our fixed charge coverage ratio was approximately 4.40x.

ITEM 3. | Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk
Our exposure to market risks on financial instruments includes interest rate risk on our Term Loan credit agreement and ABL Credit Agreement. As of June 30, 2021, there were $129.5 million in borrowings outstanding under our credit agreements. The reference interest rate applied to borrowings under the Credit Agreements is adjusted, at our option, at one, two, three, or six month intervals for LIBOR-based borrowings (or daily in the case of alternative based rate borrowings). A one percentage point increase or decrease in interest rates, based on outstanding credit facilities' borrowings of $129.5 million, would have an approximate $1.3 million annual effect on interest expense.
21

ITEM 4. | Controls and Procedures

As of June 30, 2021, our Chief Executive Officer (CEO) and Chief Financial Officer (CFO) have carried out, with the participation of our Disclosure Committee and management, an evaluation of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the Act). Based upon this evaluation, the CEO and CFO have concluded that our disclosure controls and procedures are effective to provide reasonable assurance that material information required to be disclosed by us in reports we file under the Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms and that information required to be disclosed by us in the reports we file or submit under the Act is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control Over Financial Reporting
