Organization Consolidation And Presentation Of Financial Statements [Abstract] |
Reportable Segments | We report our business in three reportable segments: Packaging, Paper, and Corporate and Other. Our Packaging segment produces a wide variety of corrugated packaging products. The Paper segment manufactures and sells a range of communication-based papers. During the second quarter of 2018, the Company discontinued the production of uncoated free sheet and coated one-side grades at the Wallula, Washington mill and converted the No. 3 machine to a virgin kraft linerboard machine. Subsequent to the date of conversion in May 2018, operating results for the Wallula mill are primarily included in the Packaging segment. Corporate and other includes support staff services and related assets and liabilities, transportation assets, and activity related to other ancillary support operations. For more information about our segments, see Note 18 Segment Information. In these consolidated financial statements, certain amounts in prior periods' consolidated financial statements have been reclassified to conform with the current period presentation.
Basis of Accounting and Presentation | The consolidated financial statements of PCA as of September 30, 2018 and for the three and nine months ended September 30, 2018 and 2017 are unaudited but include all adjustments (consisting only of normal recurring adjustments) that management considers necessary for a fair presentation of such financial statements. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with Article 10 of Regulation S-X of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete audited financial statements. Operating results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. These consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2017.
Use of Estimates | The preparation of the consolidated financial statements involves the use of estimates and accruals. Actual results may vary from those estimates.
Consolidation | The consolidated financial statements include the accounts of PCA and its majority-owned subsidiaries after elimination of intercompany balances and transactions.
New and Recently Adopted Accounting Pronouncements | 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 for the three and nine months ended September 30, 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 three and nine months ended September 30, 2018, this amount totaled $6.9 million and $20.0 million, respectively. 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 $0.3 million and $0.9 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 three and nine months ended September 30, 2017, 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 August 2018, the Financial Accounting Standards Board (“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. In February 2018, the FASB issued ASU 2018-02 (Topic 220): Income Statement – R eporting 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 does not expect this ASU to have a material impact on the Company’s financial position, results of operations, or cash flow. In February 2016, the FASB issued ASU 2016-02 (Topic 842): Leases. This ASU amends a number of aspects of lease accounting, including requiring lessees to recognize operating leases with a term greater than one year on their balance sheet as a right-of-use asset and corresponding lease liability, measured at the present value of the lease payments. Additionally, the guidance requires qualitative and quantitative disclosures designed to assess the amount, timing and uncertainty of cash flows arising from leases. In July 2018, the FASB issued ASU 2018-10: Codification Improvements to Topic 842, Leases and ASU 2018-11: Leases (Topic 842): Targeted Improvements. These ASUs provide clarification to the lease standard and allow entities an optional transition method for implementing ASU 2016-02 and a lessor practical expedient for separating lease and non-lease components. The optional transition method allows companies the option to use the effective date as the date of initial application on transition. The Company plans to elect this transition method, and as a result, we will not adjust our comparative period financial information or make the new required lease disclosures for periods before the effective date. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and early adoption is permitted. We are in the process of implementing changes to our systems and processes in conjunction with our review of existing lease agreements, which primarily consist of equipment and real estate leases. In addition, we are currently working with a vendor to implement a technology tool to assist with the accounting and reporting requirements of the new standard. We will adopt Topic 842 effective January 1, 2019 and expect to elect certain available transitional practical expedients. We are still in the process of determining the effects on our financial statements but do expect to recognize a liability and corresponding asset associated with in-scope operating leases. 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.
Revenue Recognition | Revenue Recognition Revenue is recognized when control of the promised goods or services is transferred to customers in an amount that reflects the consideration expected to be entitled in exchange for those goods or services. Sales, value added, and other taxes collected concurrently with revenue-producing activities are excluded from revenue. The following table presents our revenues disaggregated by product line (dollars in millions):
