Item 9A. CONTROLS AND PROCEDURES

Controls and Procedures

PCA maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934) that are designed to provide reasonable assurance that information required to be disclosed in PCA’s filings under the Securities Exchange Act is recorded, processed, summarized and reported within the periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to PCA’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

On October 25, 2013, PCA acquired Boise Inc. ("Boise"). PCA is in the process of integrating Boise into its operations. PCA is analyzing, evaluating, and where necessary, will implement changes in controls and procedures relating to the Boise business as such integration proceeds. As a result, this process may result in additions or changes to PCA's internal control over financial reporting. Except as it relates to the acquisition of Boise, there was no change in PCA's internal control over financial reporting during the most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect PCA's internal control over financial reporting.

Prior to filing this report, PCA completed an evaluation under the supervision and with the participation of PCA’s management, including PCA’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of PCA’s disclosure controls and procedures as of December 31, 2013. The evaluation of PCA’s disclosure controls and procedures included a review of the controls’ objectives and design, PCA’s implementation of the controls and the effect of the controls on the information generated for use in this report, but excluded the operations acquired from Boise. Based on this evaluation, PCA’s Chief Executive Officer and Chief Financial Officer concluded that PCA’s disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2013.

Management’s Report on Internal Control Over Financial Reporting

PCA’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Company’s assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only with proper authorizations; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, PCA’s internal control over financial reporting may not prevent or detect misstatements. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

PCA’s management, under the supervision of and with the participation of the Chief Executive Officer and Chief Financial Officer, assessed the Company’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment and excluding the operations acquired from Boise, PCA’s management concluded that its internal control over financial reporting was effective as of December 31, 2013, based on the specified criteria.

Ernst & Young LLP, the independent registered public accounting firm that audited PCA’s financial statements included in this Form 10-K, has also audited the effectiveness of the Company’s internal control over financial reporting. Their attestation report precedes PCA’s audited financial statements included elsewhere in this report.

Changes in Internal Control Over Financial Reporting

Except as it relates to the acquisition of Boise on October 25, 2013, there have been no changes in our internal control over financial reporting during the quarter ended December 31, 2013, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Due to the timing of the acquisition, we excluded Boise from our evaluation of the effectiveness of internal control over financial reporting. Boise’s net sales, net income, and total assets represented approximately 12% of PCA’s 2013 consolidated net sales, 14% of 2013 consolidated net income, and 52% of total consolidated assets at December 31, 2013, respectively.
