Accounting Policies [Abstract] |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. We adjust such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates will be reflected in the consolidated financial statements in future periods.
Revenue Recognition | Revenue Recognition We recognize revenue when control of the promised goods or services is transferred to customers in an amount that reflects the consideration expected to be received in exchange for those goods or services. The timing of revenue recognition for most goods and services occurs when performance obligations under the terms of a contract with the customer are satisfied. This occurs with the transfer of control of our products at a specific point in time. For most packaging and paper products, revenue is recognized when the product is shipped from the mill or from our manufacturing facility to our customer. Shipping and handling fees billed to a customer are recorded on a gross basis in “Net sales”, with the corresponding shipping and handling costs included in “Cost of sales” in the concurrent period as the revenue is recorded. We present taxes collected from customers and remitted to governmental authorities on a net basis in our Consolidated Statements of Income. In January 2018, the Company adopted ASU 2014-09 (Topic 606): Revenue from Contracts with Customers. See Note 3, Revenue, for more information.
Planned Major Maintenance Costs | Planned Major Maintenance Costs The Company accounts for its planned major maintenance activities in accordance with ASC 360, Property, Plant, and Equipment, using the deferral method. All maintenance costs incurred during the year are expensed in the year in which the maintenance activity occurs.
Share-Based Compensation | Share-Based Compensation We recognize compensation expense for awards granted under the PCA long-term equity incentive plans based on the fair value on the grant date. We recognize the cost of the equity awards expected to vest over the period the awards vest. See Note 13, Share-Based Compensation, for more information.
Research and Development | Research and Development Research and development costs are expensed as incurred. The amount charged to expense was $14.4 million, $12.8 million, and $13.3 million for the years ended December 31, 2018, 2017, and 2016, respectively.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents include all cash balances and highly liquid investments with a stated maturity of three months or less. Cash equivalents are stated at cost, which approximates market. Cash and cash equivalents totaled $361.5 million and $216.9 million at December 31, 2018 and 2017, respectively, which included cash equivalents of $311.1 million and $160.2 million, respectively. At December 31, 2018 and 2017, we had $2.3 million and $1.8 million, respectively, of cash at our operations outside the United States.
Trade Accounts Receivable, Allowance for Doubtful Accounts, and Customer Deductions | Trade Accounts Receivable, Allowance for Doubtful Accounts, and Customer Deductions Trade accounts receivable are stated at the amount we expect to collect. The collectability of our accounts receivable is based upon a combination of factors. In circumstances where a specific customer is unable to meet its financial obligations to PCA (e.g., bankruptcy filings, substantial downgrading of credit sources), a specific reserve for bad debts is recorded against amounts due to the Company to reduce the net recorded receivable to the amount the Company reasonably believes will be collected. For all other customers, reserves for bad debts are recognized based on historical collection experience. If collection experience deteriorates (i.e., higher than expected defaults or an unexpected material adverse change in a major customer’s ability to meet its financial obligations to the Company), the estimate of the recoverability of amounts due could be reduced by a material amount. We periodically review our allowance for doubtful accounts and adjustments to the valuation allowance are recorded as income or expense. Trade accounts receivable balances that remain outstanding after we have used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable. At December 31, 2018 and 2017, the allowance for doubtful accounts was $4.6 million and $4.2 million, respectively. The customer deductions reserve represents the estimated amount required for customer returns, allowances, and earned discounts. Based on the Company’s experience, customer returns, allowances, and earned discounts have averaged approximately 1% of gross selling price. Accordingly, PCA reserves 1% of its open customer accounts receivable balance for these items. The reserves for customer deductions of $9.0 million and $8.4 million at December 31, 2018 and 2017, respectively, are also included as a reduction of the accounts receivable balance.
Derivative Instruments and Hedging Activities | Derivative Instruments and Hedging Activities The Company records its derivatives, if any, in accordance with ASC 815, Derivatives and Hedging. The guidance requires the Company to recognize derivative instruments as either assets or liabilities on the balance sheet at fair value. The accounting for changes in the fair value of a derivative depends on the intended use and designation of the derivative instrument. For a derivative designated as a fair value hedge, the gain or loss on the derivative is recognized in earnings in the period of change at fair value together with the offsetting gain or loss on the hedged item. For a derivative instrument designated as a cash flow hedge, the effective portion of the derivative’s gain or loss is initially reported as a component of accumulated other comprehensive income (loss) (AOCI) and is subsequently recognized in earnings when the hedged exposure affects earnings. The ineffective portion of the gain or loss is recognized in earnings. We were not party to any derivative-based arrangements at December 31, 2018 and 2017.
Fair Value Measurements | Fair Value Measurements PCA measures the fair value of its financial instruments in accordance with ASC 820, Fair Value Measurements and Disclosures. The guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. It is determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes the following hierarchy that prioritizes the inputs to valuation methodologies used to measure fair value: Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 — Valuations based on unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Assets that are measured at fair value using the net asset value (NAV) per share as a practical expedient are not categorized within the fair value hierarchy. Financial instruments measured at fair value on a recurring basis include the fair value of our pension and postretirement benefit assets and liabilities. See Note 11, Employee Benefit Plans and Other Postretirement Benefits, for more information. Other assets and liabilities measured and recognized at fair value on a nonrecurring basis include assets acquired and liabilities assumed in acquisitions and our asset retirement obligations. Given the nature of these assets and liabilities, evaluating their fair value from the perspective of a market participant is inherently complex. Assumptions and estimates about future values can be affected by a variety of internal and external factors. Changes in these factors may require us to revise our estimates and could require us to retroactively adjust provisional amounts that we recorded for the fair values of assets acquired and liabilities assumed in connection with business combinations. These adjustments could have a material effect on our financial condition and results of operations. See Note 4, Acquisitions, and Note 12, Asset Retirement Obligations, for more information.
Inventory Valuation | Inventory Valuation We value our raw materials, work in process, and finished goods inventories using lower of cost, as determined by the average cost method, or market. Supplies and materials are valued at the first-in, first-out (FIFO) or average cost methods.
Property, Plant, and Equipment | Property, Plant, and Equipment Property, plant, and equipment are recorded at cost. Cost includes expenditures for major improvements and replacements and the amount of interest cost associated with significant capital additions. Repairs and maintenance costs are expensed as incurred. When property and equipment are retired, sold, or otherwise disposed of, the asset's carrying amount and related accumulated depreciation are removed from the accounts and any gain or loss is included in “Net income” in our Consolidated Statements of Income.
Depreciation and Useful Life | Depreciation is computed on the straight-line basis over the estimated useful lives of the related assets. Assets under capital leases are depreciated on the straight-line method over the term of the lease or the useful life, if shorter. The following lives are used for the various categories of assets:
Buildings and land improvements |  | 5 to 40 years
Machinery and equipment |  | 3 to 25 years
Trucks and automobiles |  | 3 to 10 years
Furniture and fixtures |  | 3 to 20 years
Computers and hardware |  | 3 to 10 years
Leasehold improvements |  | Period of the lease or useful life, if shorter
Leases | Leases We assess lease classification as either capital or operating at lease inception or upon modification. We lease some of our locations, as well as other property and equipment, under operating leases. For purposes of determining straight-line rent expense, the lease term is calculated from the date of possession of the facility, including any periods of free rent and any renewal option periods that are reasonably assured of being exercised. In February 2016, the FASB issued ASU 2016-02 (Topic 842): Leases, which amends a number of aspects of lease accounting. The guidance of ASU 2016-02 is effective for the Company beginning in January 2019.
Long-Lived Asset Impairment | Long-Lived Asset Impairment Long-lived assets other than goodwill and other intangibles are reviewed for impairment in accordance with provisions of ASC 360, Property, Plant and Equipment. In the event that facts and circumstances indicate that the carrying amount of any long-lived assets may be impaired, an evaluation of recoverability is performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset (or group of assets) is compared to the assets (or group of assets) carrying amount to determine if a write-down to fair value is required.
Goodwill and Intangible Assets | Goodwill and Intangible Assets The Company has capitalized certain intangible assets, primarily goodwill, customer relationships, and trademarks and trade names, based on their estimated fair value at the date of acquisition. Amortization is provided for customer relationships on a straight-line basis over periods ranging from ten to 40 years, and trademarks and trade names over periods ranging from five to 20 years. Goodwill, which amounted to $917.3 million and $883.2 million for the years ended December 31, 2018 and 2017, respectively, is not amortized but is subject to an annual impairment test in accordance with ASC 350, Intangibles – Goodwill and Other. We test goodwill for impairment annually in the fourth quarter or sooner if events or changes in circumstances indicate that the carrying value of the asset may exceed fair value. Additionally, we evaluate the remaining useful lives of our finite-lived purchased intangible assets to determine whether any adjustments to the useful lives are necessary. The Company concluded that none of the goodwill or intangible assets were impaired in the 2018, 2017, and 2016 annual impairment tests. See Note 8, Goodwill and Intangible Assets, for additional information.
Pension and Postretirement Benefits | Pension and Postretirement Benefits Several estimates and assumptions are required to record pension costs and liabilities, including discount rate, return on assets, and longevity and service lives of employees. We review and update these assumptions annually unless a plan curtailment or other event occurs, requiring that we update the estimates on an interim basis. While we believe the assumptions used to measure our pension and postretirement benefit obligations are reasonable, differences in actual experience or changes in assumptions may materially affect our pension and postretirement benefit obligations and future expense. See Note 11, Employee Benefit Plans and Other Postretirement Benefits, for additional information. For postretirement health care plan accounting, the Company reviews external data and its own historical trends for health care costs to determine the health care cost trend rate assumption. In January 2018, the Company adopted ASU 2017-07, Compensation – Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which requires the presentation of non-service cost components of net periodic benefits expense to be shown separately outside the subtotal of operating income in the Consolidated Statements of Income and Comprehensive Income.
Environmental Matters | Environmental Matters Environmental expenditures that extend the life of the related property or mitigate or prevent future environmental contamination are capitalized. Liabilities are recorded for environmental contingencies when such costs are probable and reasonably estimable. These liabilities are adjusted as further information develops or circumstances change. Environmental expenditures related to existing conditions resulting from past or current operations from which no current or future benefit is discernible are expensed as incurred.
Asset Retirement Obligations | Asset Retirement Obligations The Company accounts for its retirement obligations related predominantly to landfill closure, wastewater treatment pond dredging, closed-site monitoring costs, and certain leasehold improvements under ASC 410, Asset Retirement and Environmental Obligations, which requires recognition of legal obligations associated with the retirement of long-lived assets whether these assets are owned or leased. These legal obligations are recognized at fair value at the time that the obligations are incurred. When we record the liability, we capitalize the cost by increasing the carrying amount of the related long-lived asset, which is amortized to expense over the useful life of the asset. See Note 12, Asset Retirement Obligations, for additional information.
Deferred Debt Issuance Costs | Deferred Debt Issuance Costs PCA has capitalized certain costs related to obtaining its financing. These costs are amortized to interest expense using the effective interest rate method over the terms of the related financing, which range from three to ten years. At December 31, 2018 and 2017 deferred debt issuance costs were $12.6 million and $15.3 million, respectively, and were recorded in “Long-Term Debt” on our Consolidated Balance Sheets.
Cutting Rights and Fiber Farms | Cutting Rights and Fiber Farms We lease the cutting rights to approximately 75,000 acres of timberland, and we lease 3,000 acres of land where we operate fiber farms as a source of future fiber supply. For our cutting rights and fiber farms, we capitalize the annual lease payments and reforestation costs associated with these leases. Costs are recorded as depletion when the timber or fiber is harvested and used in operations or sold to customers. Capitalized long-term lease costs for our cutting rights and fiber farms, primarily recorded in “Other long-term assets” on our Consolidated Balance Sheets, were $22.4 million and $31.5 million as of December 31, 2018 and 2017, respectively. The amount of depletion expense was $7.6 million, $5.2 million, and $4.7 million for the years ended December 31, 2018, 2017, and 2016, respectively. Additionally, in conjunction with the conversion of the No. 3 machine at the Wallula mill to kraft linerboard, management performed a recoverability test on associated fiber farms in 2018 and 2017 and deemed the asset group to not be fully recoverable. As a result of the recoverability calculation on the fiber farm asset group, the Company recorded an impairment loss of $3.1 million and $13.5 million during 2018 and 2017, respectively.
Deferred Software Costs | Deferred Software Costs PCA capitalizes costs related to the purchase and development of software, which is used in its business operations. The costs attributable to these software systems are amortized over their estimated useful lives based on various factors such as the effects of obsolescence, technology, and other economic factors. Net capitalized software costs recorded in “Other long-term assets” on our Consolidated Balance Sheets were $1.6 million and $3.3 million for the years ended December 31, 2018 and 2017, respectively. Software amortization expense was $2.1 million, $2.3 million, and $2.5 million for the years ended December 31, 2018, 2017, and 2016, respectively.
Income Taxes | Income Taxes PCA utilizes the liability method of accounting for income taxes whereby it recognizes deferred tax assets and liabilities for the future tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements. Deferred tax assets will be reduced by a valuation allowance if, based upon management’s estimates, it is more likely than not that a portion of the deferred tax assets will not be realized in a future period. The estimates utilized in the recognition of deferred tax assets are subject to revision in future periods based on new facts or circumstances. PCA’s practice is to recognize interest and penalties related to unrecognized tax benefits in income tax expense.
Trade Agreements | Trade Agreements PCA regularly trades containerboard with other manufacturers primarily to reduce shipping costs. These agreements are entered into with other producers on an annual basis, pursuant to which both parties agree to ship an identical number of tons of containerboard to each other within the agreement period. These agreements lower transportation costs by allowing each party’s containerboard mills to ship containerboard to the other party’s closer corrugated products plant. PCA tracks each shipment to ensure that the other party’s shipments to PCA match PCA’s shipments to the other party during the agreement period. Such transfers are possible because containerboard is a commodity product with no distinguishing product characteristics. These transactions are accounted for at carrying value, and revenue is not recorded as the transactions do not represent the culmination of an earnings process. The transactions are recorded into inventory accounts, and no sale or income is recorded until such inventory is converted to a finished product and sold to an end-use customer. Business Combinations The Company accounts for acquisitions under ASC 805, Business Combinations, which requires separate recognition of assets acquired and liabilities assumed from goodwill, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and liabilities assumed. During the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated financial statements. In January 2018, the Company adopted ASU 2017-01, Clarifying the Definition of a Business, which adds guidance to assist entities with evaluating whether transfers of assets and activities should be accounted for as acquisitions of assets or businesses.
Recently Adopted Accounting Standards | Recently Adopted Accounting Standards Effective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09 (Topic 606): Revenue from Contracts with Customers. This ASU supersedes the revenue recognition requirements in Topic 605 Revenue Recognition (Topic 605) and requires entities to recognize revenue when control of the promised goods or services is transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and estimates, and changes in those estimates. The Company adopted the standard utilizing the modified retrospective method, in which case the cumulative effect was recognized at the date of initial application on January 1, 2018. The adoption of the standard did not have a material effect on the Company’s financial position or results of operations; however, the following adjustment and reclassification of certain costs were made in 2018: a. The Company ships a portion of its products to customers under consignment agreements. These products do not have an alternative use, and, under the new standard, revenue associated with these products is required to be recognized earlier than under prior revenue recognition standards. Utilizing the modified retrospective method, the cumulative impact of adopting the new standard resulted in an increase of approximately $1.6 million, net of tax, to opening retained earnings as of January 1, 2018. b. The new revenue standard also provides additional clarity concerning contract fulfillment costs, which resulted in certain costs being classified as cost of sales rather than selling, general and administrative expenses beginning January 1, 2018. For the year ended December 31, 2018, this amount totaled $28.2 million. See Note 3, Revenue, for more information. Effective January 1, 2018, the Company adopted ASU 2017-07, Compensation: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The guidance in this update requires that an employer disaggregate the service cost component from the other components of net benefit cost. Non-service cost components of net periodic benefit cost are required to be presented in the income statement separately from the service cost component and outside the subtotal of operating income. The update also allows only the service cost component to be eligible for capitalization for internally developed capital projects. The amendments in this update are applied retrospectively for the income statement presentations and prospectively for the capitalization of service costs. The adoption of this ASU retrospectively resulted in a $1.3 million and $3.0 million reclassification between cost of sales and selling, general and administrative expenses (both components of income from operations) and interest expense, net and other (a component outside of income from operations) for the years ended December 31, 2017 and 2016, respectively. Effective January 1, 2018, the Company adopted ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting, which clarifies what changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. This ASU will be applied prospectively when changes to the terms or conditions of a share-based payment award occur. Effective January 1, 2018, the Company adopted ASU 2017-01 (Topic 805): Clarifying the Definition of a Business, which amends the guidance in ASC 805, Business Combinations. The ASU changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. Under the new guidance, an entity first determines whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set is not a business. If it is not met, the entity then evaluates whether the set meets the requirements that a business include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. The ASU defines an output as “the result of inputs and processes applied to those inputs that provide goods or services to customers, investment income (such as dividends or interest), or other revenues.” The ASU will be applied prospectively to any transactions subsequent to adoption. Effective January 1, 2018, the Company adopted ASU 2016-15 (Topic 230), Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. This ASU adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The adoption of this guidance did not have a material impact on the Company's financial condition, results of operations, or cash flows.
New Accounting Standards Not Yet Adopted | New Accounting Standards Not Yet Adopted In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02 (Topic 842): Leases, which requires lessees to recognize a right-of-use (“ROU”) asset and a lease liability on the balance sheet for all leases, with the exception of short-term leases, and expands disclosures about leasing arrangements for both lessees and lessors, among other items. The new standard is effective for the Company beginning January 1, 2019. In July 2018, the FASB issued ASU No. 2018-11, which provides a modified retrospective transition method where an entity can elect to apply the transition provisions at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Under this method, comparative prior period financial information is not restated. Effective January 1, 2019, the Company will adopt the new lease accounting standard using the modified retrospective transition method at the adoption date with prior periods not restated. In addition, we will elect the package of practical expedients permitted under the transition guidance within the new standard, which permits us to not reassess our prior conclusions about lease identification, lease classification and initial direct costs. We will also elect the practical expedient related to land easements, allowing us to carry forward our current accounting treatment for existing agreements on land easements, which are not accounted for as leases. We will elect the short-term lease recognition exemption, which permits us to exclude short-term leases (i.e. leases with terms of 12 months or less) from the recognition requirements of this standard. In preparing for the transition of the new standard, we identified and assessed appropriate changes to our business processes, systems and controls to support the new leasing accounting requirements and disclosures under the new standard. We expect that adoption of this standard will result in recognition of lease liabilities of approximately $220 million to $240 million as of January 1, 2019, with corresponding ROU assets of the same amount based on the present value of the remaining minimum rental payments for existing operating leases. We do not expect to make any cumulative-effect adjustment to retained earnings as a result of the adoption of this standard. We do not believe that adoption of this ASU will have a material impact on our consolidated net earnings, liquidity, or debt covenants under our current debt agreements. In February 2018, the FASB issued ASU 2018-02 (Topic 220): Income Statement – Reporting Comprehensive Income – Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows for optional reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects resulting from the enactment of H.R.1 (P.L. 115-97), originally known as the “Tax Cuts and Jobs Act,” in December 2017. An entity that elects to reclassify these amounts must reclassify stranded tax effects related to the change in federal tax rate for all items accounted for in other comprehensive income (e.g., pension and postretirement benefits and cash flow hedges). Entities may also elect to reclassify other stranded tax effects that relate to the Act but do not directly relate to the change in the federal tax rate (e.g., state taxes). Upon adoption of ASU 2018-02, entities are required to disclose their policy for releasing the income tax effects from accumulated other comprehensive income. ASU 2018-02 is effective for annual periods beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently finalizing its evaluation of this guidance but does not expect this ASU to have a material impact on the Company’s financial position, results of operations, or cash flow. In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 removes certain disclosures that are not considered cost beneficial, clarifies certain required disclosures and adds additional disclosures. The ASU is effective for annual periods beginning after December 31, 2020, with early adoption permitted. The amendments in ASU 2018-14 would need to be applied on a retrospective basis. The Company is currently evaluating the impact this guidance will have on its related disclosures. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 removes or modifies certain disclosure requirements and adds additional requirements to improve the usefulness of the fair value measurement disclosure for financial statement users. The ASU is effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. Certain amendments of ASU 2018-13 are required to be applied prospectively for the first interim period of the initial year of adoption. All other amendments need to be applied retrospectively. The Company is currently evaluating the impact of the new guidance. There were no other accounting standards recently issued that had or are expected to have a material impact on our financial position or results of operations.
