Condensed Notes to Unaudited Quarterly Consolidated Financial Statements
1. Nature of Operations and Basis of Presentation
Packaging Corporation of America ("we," "us," "our," PCA," or the "Company") was incorporated on January 25, 1999. In April 1999, PCA acquired the containerboard and corrugated packaging products business of Pactiv Corporation (Pactiv), formerly known as Tenneco Packaging, Inc., a wholly owned subsidiary of Tenneco Inc. We are a large diverse manufacturer of both packaging and paper products. We are headquartered in Lake Forest, Illinois and we operate primarily in the United States.
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 white papers, including communication-based papers and pressure sensitive papers, and market pulp. 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 15 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. As previously disclosed in Note 20, Quarterly Results of Operations, of the Notes to Consolidated Financial Statements in "Part II, Item 8. Financial Statements and Supplementary Data" of our 2015 Annual Report on Form 10-K, to correct an error in the 2015 presentation, a total of $6.0 million was reclassified from "Selling, general, and administrative expenses" to "Cost of Sales" for both the three and six months ended June 30, 2015.
The consolidated financial statements of PCA as of June 30, 2016 and for the three and six months ended June 30, 2016 and 2015 are unaudited but include all adjustments (consisting only of normal recurring adjustments) that management considers necessary for a fair presentation of such financial statements. The preparation of the consolidated financial statements involves the use of estimates and accruals. Actual results may vary from those estimates. 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 SEC Regulation S-X. 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 six months ended June 30, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016. These consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2015.
The consolidated financial statements include the accounts of PCA and its majority-owned subsidiaries after elimination of intercompany balances and transactions.

___________

(a) | The three and six months ended June 30, 2016 include facilities closure costs related to corrugated products facilities and a paper products facility.

(b) | The three and six months ended June 30, 2016 include acquisition-related costs for the announced TimBar Corporation acquisition.

4. Income Taxes
For the three months ended June 30, 2016 and 2015 we recorded $61.8 million and $61.4 million of income tax expense and had an effective tax rate of 34.8% and 35.0%, respectively. The decrease in our effective tax rate for the three months ended June 30, 2016 compared with the same period in 2015, was primarily due to the 2016 benefit of federal income tax credits that were not available at June 30, 2015 due to the expiration and later reinstatement on December 18, 2015 as part of the Protecting Americans from Tax Hikes Act (PATH Act).
For the six months ended June 30, 2016 and 2015, we recorded $117.3 million and $108.5 million of income tax expense and had an effective tax rate of 34.8% and 34.6%, respectively. The increase in our effective tax rate for the six months ended June 30, 2016 compared with the same period in 2015, was primarily due to the 2015 favorable closure of a Federal audit for tax years 2010 through 2012 and the resulting release of uncertain tax positions and favorable state law changes, partially offset by expired federal income tax credits later reinstated in the PATH Act.
Our effective tax rate may differ from the federal statutory income tax rate of 35.0%, due primarily to the effect of the domestic manufacturing deduction and state and local income taxes.
During the three and six months ended June 30, 2016 there were no significant changes to our uncertain tax positions. For more information, see Note 6, Income Taxes, of the Notes to Consolidated Financial Statements in "Part II, Item 8. Financial Statements and Supplementary Data" of our 2015 Annual Report on Form 10-K.
During the six months ended June 30, 2016 and 2015 cash paid for taxes, net of refunds received, was $83.3 million and $87.8 million, respectively.

For both the three months ended June 30, 2016 and 2015 amortization of treasury lock settlements was $1.4 million, and for both the six months ended June 30, 2016 and 2015, amortization of treasury lock settlements was $2.8 million. For the three months ended June 30, 2016 and 2015 amortization of financing costs was $0.5 million and $0.4 million, respectively, and during the six months ended for both June 30, 2016 and 2015, amortization of financing costs was $0.9 million.
For more information on our long-term debt and interest rates on that debt, see Note 10, Debt, of the Notes to Consolidated Financial Statements in "Part II, Item 8. Financial Statements and Supplementary Data" of our 2015 Annual Report on Form 10-K.
At June 30, 2016 we had $1,650.0 million of fixed-rate senior notes and $658.8 million of variable-rate term loans outstanding. At June 30, 2016 the fair value of our fixed-rate debt was estimated to be $1,773.0 million. The difference between the book value and fair value is due to the difference between the period-end market interest rate and the stated rate of our fixed-rate debt. We estimated the fair value of our fixed-rate debt using quoted market prices (Level 2 inputs) within the fair value hierarchy, which is further defined in Note 2, Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements in "Part II, Item 8. Financial Statements and Supplementary Data" of our 2015 Annual Report on Form 10-K. The fair value of our variable-rate term debt approximates the carrying amount as our cost of borrowing is variable and approximates current market rates.
10. Employee Benefit Plans and Other Postretirement Benefits
The components of net periodic benefit cost for our pension plans were as follows (dollars in millions):

| Pension Plans
| Three Months Ended June 30 |  | Six Months Ended June 30
| 2016 |  | 2015 |  | 2016 |  | 2015
Service cost | $ | 6.1 |  |  | $ | 6.0 |  |  | $ | 12.2 |  |  | $ | 11.8 |
Interest cost | 10.2 |  |  | 11.5 |  |  | 20.4 |  |  | 23.0 |
Expected return on plan assets | (12.4 | ) |  | (13.3 | ) |  | (24.8 | ) |  | (26.6 | )
Net amortization of unrecognized amounts |  |  |  |  |  |  |
Prior service cost | 1.4 |  |  | 1.4 |  |  | 2.8 |  |  | 2.8 |
Actuarial loss | 1.4 |  |  | 2.2 |  |  | 2.8 |  |  | 4.3 |
Net periodic benefit cost | $ | 6.7 |  |  | $ | 7.8 |  |  | $ | 13.4 |  |  | $ | 15.3 |

In April 2016, the Company provided notice to eligible participants that the Salaried Retiree Medical Plan would be frozen as of December 31, 2016. As a result of the freeze, eligible plan participants who do not retire and elect coverage before December 31, 2016 lose benefits attributable to service already rendered. In accordance with Accounting Standards Codification (ASC) 715, "Compensation--Retirement Benefits", the Company remeasured the Salaried Retiree Medical Plan benefit obligation using current assumptions, resulting in a decrease in the benefit obligation of $5.1 million with a corresponding increase in accumulated other comprehensive income of $3.1 million and deferred income taxes of $2.0 million.
PCA makes pension plan contributions that are sufficient to fund its actuarially determined costs, generally equal to the minimum amounts required by the Employee Retirement Income Security Act (ERISA). During the three and six months ended June 30, 2016 and 2015 payments to our nonqualified pension plans were insignificant. We made a contribution of $3.7 million to our qualified plans during the three and six months ended June 30, 2016; however, we did not make a contribution to our qualified plans during the same periods in 2015. We expect to contribute at least the estimated required minimum contributions to our qualified plans of approximately $27.0 million in 2016.

Net periodic benefit cost | $ | 0.2 |  |  | $ | 0.7 |  |  | $ | 0.4 |  |  | $ | 1.5 |

11. Share-Based Compensation
The Company has a long-term equity incentive plan, which allows for grants of restricted stock, performance awards, stock appreciation rights, and stock options to directors, officers, and employees, as well as others who engage in services for PCA. The Company has not granted option awards since 2007. The plan, as amended, terminates May 1, 2023 and authorizes 10.6 million shares of common stock for grant over the life of the plan. As of June 30, 2016, 1.2 million shares were available for future issuance under the plan. Forfeitures are added back to the pool of shares of common stock available to be granted at a future date.
The following table presents restricted stock and performance unit award activity for the six months ended June 30, 2016:

| Restricted Stock |  | Performance Units
| Shares |  | Weighted Average Grant- Date Fair Value |  | Shares |  | Weighted Average Grant- Date Fair Value
Outstanding at January 1, 2016 | 1,007,794 |  |  | $ | 49.47 |  |  | 175,675 |  |  | $ | 59.94 |
Granted | 242,835 |  |  | 67.48 |  |  | 77,017 |  |  | 67.57 |
Vested (a) | (409,815 | ) |  | 32.64 |  |  | (20,604 | ) |  | 57.58 |
Forfeitures | (14,440 | ) |  | 56.69 |  |  | — |  |  | — |
Outstanding at June 30, 2016 | 826,374 |  |  | $ | 62.99 |  |  | 232,088 |  |  | $ | 62.68 |

___________

(a) | Upon vesting of the performance unit awards, PCA issued 21,111 shares of its common stock, which included 507 shares for dividends accrued during the vesting period.

Compensation Expense
Our share-based compensation expense is recorded in "Selling, general, and administrative expenses". Compensation expense for share-based awards recognized in the Consolidated Statements of Income, net of forfeitures, was as follows (dollars in millions):

| Three Months Ended June 30 |  | Six Months Ended June 30
| 2016 |  | 2015 |  | 2016 |  | 2015
Restricted stock | $ | 3.9 |  |  | $ | 4.4 |  |  | $ | 8.8 |  |  | $ | 8.0 |
Performance units | 0.8 |  |  | 0.5 |  |  | 1.5 |  |  | 1.1 |
Total share-based compensation expense | 4.7 |  |  | 4.9 |  |  | 10.3 |  |  | 9.1 |
Income tax benefit | (1.8 | ) |  | (1.9 | ) |  | (4.0 | ) |  | (3.5 | )
Share-based compensation expense, net of tax benefit | $ | 2.9 |  |  | $ | 3.0 |  |  | $ | 6.3 |  |  | $ | 5.6 |

The fair value of restricted stock and performance units is determined based on the closing price of the Company’s common stock on the grant date. As PCA’s Board of Directors has the ability to accelerate vesting of share-based awards upon
9

an employee’s retirement, the Company accelerates the recognition of compensation expense for certain employees approaching normal retirement age.
The unrecognized compensation expense for all share-based awards at June 30, 2016 was as follows (dollars in millions):

| June 30, 2016
| Unrecognized Compensation Expense |  | Remaining Weighted Average Recognition Period (in years)
Restricted stock | $ | 34.4 |  |  | 3.0
Performance units | 10.0 |  |  | 3.2
Total unrecognized share-based compensation expense | $ | 44.4 |  |  | 3.1

12. Stockholders' Equity
Dividends
During the six months ended June 30, 2016, we paid $104.9 million of dividends to shareholders. On May 18, 2016 PCA's Board of Directors declared a regular quarterly cash dividend of $0.55 per share, which was paid on July 15, 2016 to shareholders of record as of June 15, 2016. The July 2016 dividend payment was $51.8 million.
Repurchases of Common Stock
On February 25, 2016 PCA announced that its Board of Directors authorized the repurchase of an additional $200.0 million of the Company’s outstanding common stock. Repurchases may be made from time to time in open market or privately negotiated transactions in accordance with applicable securities regulations. The timing and amount of repurchases will be determined by the Company in its discretion based on factors such as PCA’s stock price and market and business conditions.
During the six months ended June 30, 2016, we paid $100.3 million to repurchase 1,987,187 shares of common stock.
Accumulated Other Comprehensive Income (Loss)
Changes in accumulated other comprehensive income (loss) (AOCI) by component were as follows. Amounts in parentheses indicate losses (dollars in millions):

____________

(a) | This AOCI component is included in interest expense, net. Amount relates to the amortization of the effective portion of treasury lock derivative instruments recorded in AOCI. The net amount of settlement gains or losses on derivative instruments included in AOCI to be amortized over the next 12 months is a net loss of $5.7 million ($3.5 million after tax). For a discussion of treasury lock derivative instrument activity, see Note 14, Derivative Instruments and Hedging Activities, of the Notes to Consolidated Financial Statements in "Part II, Item 8. Financial Statements and Supplementary Data" of our 2015 Annual Report on Form 10-K.

(b) | These AOCI components are included in the computation of net pension and postretirement benefit costs. See Note 10, Employee Benefit Plans and Other Postretirement Benefits, for additional information.

13. Concentrations of Risk
Our Paper segment has had a long-standing commercial and contractual relationship with Office Depot, our largest customer in the paper business. This relationship exposes us to a significant concentration of business and financial risk. Our sales to Office Depot represent approximately 8% and 10% of our total Company sales revenue, for the six months ended June 30, 2016 and 2015, respectively, and approximately 41% and 45% of our Paper segment sales revenue for both those periods, respectively. At June 30, 2016 and December 31, 2015 we had $28.9 million and $39.5 million of accounts receivable due from Office Depot, which represents 4% and 6% of our total Company accounts receivable, respectively.
In 2015, sales to Office Depot represented 45% of our Paper segment sales. If these sales are reduced, we would need to find new customers. We may not be able to fully replace any lost sales, and any new sales may be at lower prices or higher costs. Any significant deterioration in the financial condition of Office Depot affecting its ability to pay or any other change that affects its willingness to purchase our products will harm our business and results of operations.
During the second quarter of 2016, Office Depot and Staples terminated their merger agreement, and the acquisition of Office Depot by Staples was not completed. We continue to do business in the ordinary course with Office Depot.

14. Transactions With Related Parties
Louisiana Timber Procurement Company, L.L.C. (LTP) is a variable-interest entity that is 50% owned by PCA and 50% owned by Boise Cascade Company (Boise Cascade). LTP procures sawtimber, pulpwood, residual chips, and other residual wood fiber to meet the wood and fiber requirements of PCA and Boise Cascade in Louisiana. PCA is the primary beneficiary of LTP, and has the power to direct the activities that most significantly affect the economic performance of LTP. Therefore, we consolidate 100% of LTP in our financial statements in our Corporate and Other segment. The carrying amounts of LTP's assets and liabilities (which relate primarily to noninventory working capital items) on our Consolidated Balance Sheets were $3.9 million at June 30, 2016 and $4.5 million at December 31, 2015. During the three months ended June 30, 2016 and 2015, we recorded $17.1 million and $23.2 million, respectively, and during the six months ended June 30, 2016 and 2015 we recorded $39.3 million and $45.1 million, respectively, of LTP sales to Boise Cascade in "Net Sales" in the Consolidated Statements of Income and approximately the same amount of expenses in "Cost of Sales". The sales were at prices designed to approximate market prices.
During the three months ended June 30, 2016 and 2015 fiber purchases from related parties were $4.5 million and $5.0 million, respectively. Fiber purchases were $9.2 million and $11.3 million, respectively, during the six months ended June 30, 2016 and 2015. Most of these purchases related to chip and log purchases by LTP from Boise Cascade's wood products business. These purchases are recorded in "Cost of Sales" in the Consolidated Statements of Income.
15. Segment Information
We report our business in three reportable segments: Packaging, Paper, and Corporate and Other. These segments represent distinct businesses that are managed separately because of differing products and services. Each of these businesses requires distinct operating and marketing strategies.
Each segment's profits and losses are measured on operating profits before interest expense, net, and income taxes. For many of these allocated expenses, the related assets and liabilities remain in the Corporate and Other segment.
Selected financial information by reportable segment was as follows (dollars in millions):

___________

(a) | The three and six months ended June 30, 2016 include $1.7 million and $4.5 million, respectively, of closure costs related to corrugated products facilities and a paper products facility. The closure costs are recorded within "Other expense, net" and "Cost of sales", as appropriate.

The three and six months ended June 30, 2016 include $0.3 million of acquisition-related costs for the announced TimBar Corporation acquisition, which we recorded in "Other expense, net".
The three and six months ended June 30, 2016 include $0.9 million of costs related to our withdrawal from a multiemployer pension plan for one of our corrugated products facilities.

(b) | The three and six months ended June 30, 2015 include $1.0 million of income and $9.3 million of expense, respectively, related to restructuring charges at our mill in DeRidder, Louisiana, which were recorded in "Other expense, net" and "Cost of sales", as appropriate.

The three and six months ended June 30, 2015 include $1.7 million and $2.6 million of Boise acquisition integration-related and other costs, respectively. These costs primarily relate to professional fees, severance, retention, relocation, travel, and other integration-related costs, and are mostly recorded in "Other expense, net".

(c) | The three and six months ended June 30, 2015 include $2.0 million and $4.6 million, respectively, of Boise acquisition integration-related and other costs, mostly recorded in "Other expense, net". Boise acquisition integration-related and other costs, primarily recorded in "Other expense, net".

16. New and Recently Adopted Accounting Standards
In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09 (Topic 718): Improvements to Employee Share-Based Payment Accounting. This ASU is intended to improve the accounting for share-based payment transactions as part of the FASB's simplification initiative. Under the ASU, all excess tax benefits and tax deficiencies will be recorded as an income tax benefit or expense in the income statement. The ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those years for public business entities. We are evaluating the timing and effects of the adoption of this ASU on our financial statements.
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. This ASU will be effective for us beginning in our first quarter of 2019 and early adoption is permitted. This ASU is required to be adopted using a modified retrospective approach. We are evaluating the timing and effects of the adoption of this ASU on our financial statements.
13

Effective January 1, 2016, the Company adopted ASU 2015-03 (Topic 835): Simplifying the Presentation of Debt Issuance Costs. This ASU conforms the presentation of debt issuance costs with that required for debt discounts under U.S. Generally Accepted Accounting Principles (GAAP). Under the ASU, debt issuance costs are presented in the balance sheet as a direct deduction from the related liability rather than as an asset. We applied this guidance retrospectively, as required, and reclassified $12.3 million from "Other long-term assets" to "Long-term debt" on our December 31, 2015 Consolidated Balance Sheet to conform with current period presentation. At June 30, 2016 deferred financing costs were $11.5 million.
In July 2015, the FASB issued ASU 2015-11 (Topic 330): Simplifying the Measurement of Inventory. This ASU addresses only the measurement of inventory if its value declines or is impaired. The guidance on determining the cost of inventory is not amended. We continue to apply average cost to determine the cost of inventory and will then compare that to the net realizable value to determine if an inventory write-down is necessary. The ASU is effective January 1, 2017, and we do not expect it to have a material effect on our financial position or results of operations.
In May 2014, the FASB issued ASU 2014-09 (Topic 606): Revenue from Contracts with Customers. This ASU amends the guidance for revenue recognition to replace numerous, industry-specific requirements and converges areas under this topic with those of the International Financial Reporting Standards. The ASU implements a five-step process for customer contract revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards. The amendment also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting revenue gross versus net), which clarifies gross versus net revenue reporting when another party is involved in the transaction. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers-Identifying Performance Obligations and Licensing, which amends the revenue guidance on identifying performance obligations and accounting for licenses of intellectual property. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers - Narrow-Scope Improvements and Practical Expedients, which provides narrow-scope improvements to the guidance on collectability, non-cash consideration, and completed contracts at transition. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The standard will be effective for reporting periods beginning after December 15, 2017. We are still assessing the impact of ASU 2014-09, but we do not believe it will have a material effect on our financial position or results of operations.
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.
17. Commitments, Guarantees, Indemnifications and Legal Proceedings
We have financial commitments and obligations that arise in the ordinary course of our business. These include long-term debt, capital commitments, lease obligations, and purchase commitments for goods and services, and legal proceedings, all of which are discussed in Note 10, Debt, and Note 19, Commitments, Guarantees, Indemnifications, and Legal Proceedings, of the Notes to Consolidated Financial Statements in "Part II, Item 8. Financial Statements and Supplementary Data" of our 2015 Annual Report on Form 10-K.
Guarantees and Indemnifications
We provide guarantees, indemnifications, and other assurances to third parties in the normal course of our business. These include tort indemnifications, product guarantees, environmental assurances, and representations and warranties in commercial agreements. At June 30, 2016 we are not aware of any material liabilities arising from any guarantee, indemnification, or financial assurance we have provided. If we determined such a liability was probable and subject to reasonable determination, we would accrue for it at that time.
Legal proceedings

Overview
PCA is the fourth largest producer of containerboard and corrugated packaging products in the United States and the third largest producer of uncoated freesheet paper in North America, based on production capacity. We operate five containerboard mills, three paper mills, and 90 corrugated products manufacturing plants. Our corrugated products manufacturing plants produce a wide variety of corrugated packaging products, including conventional shipping containers used to protect and transport manufactured goods, multi-color boxes and displays with strong visual appeal that help to merchandise the packaged product in retail locations, and honeycomb protective packaging. In addition, we are a large producer of packaging for meat, fresh fruit and vegetables, processed food, beverages, and other industrial and consumer products. We also manufacture and sell white papers, including both commodity and specialty papers, which may have custom or specialized features such as colors, coatings, high brightness, and recycled content. We operate primarily in the United States.
This Item 2 is intended to supplement, and should be read in conjunction with, "Management’s Discussion and Analysis of Financial Condition and Results of Operations" included in our 2015 Annual Report on Form 10-K.
Executive Summary
Second quarter net sales were $1.42 billion in 2016 and $1.45 billion in 2015. We reported $116 million of net income, or $1.23 per diluted share, during the second quarter of 2016, compared with $114 million of net income, or $1.16 per diluted share, during the same period in 2015. Excluding the special items discussed below, we recorded $118 million of net income, or $1.25 per diluted share, during the second quarter of 2016, compared with $116 million, or $1.18 per diluted share, in the second quarter of 2015. Increased earnings per share was driven primarily by higher corrugated product volumes and lower costs for energy, fiber, and freight in our packaging and paper segments, and a lower share count resulting from share repurchases. Gains were partially offset by lower domestic containerboard, corrugated products, and white paper prices and mix, lower containerboard export prices, and lower containerboard and pulp volume.
During the first six months of 2016 we reported $220 million of net income, or $2.32 per diluted share, compared with $205 million, or $2.08 per diluted share, during the same period in 2015. Excluding special items discussed below, we recorded $223 million of net income, or $2.36 per diluted share, during the first six months of 2016, compared with $215 million, or $2.19 per diluted share, in the first six months of 2015. Increased earnings per share was driven primarily by higher volumes and lower maintenance costs in our packaging segment; energy, fiber and freight costs were lower in both our packaging and
15

paper segments, and a lower share count resulting from share repurchases. Gains were partially offset by lower prices and mix in white paper, containerboard, and corrugated products.
Packaging segment income from operations was $192 million in the second quarter of 2016, compared to $195 million in the second quarter of 2015. Packaging segment earnings before interest, taxes, depreciation, amortization, and depletion (EBITDA) excluding special items was $267 million in each of the second quarters of 2016 and 2015. Compared to the second quarter of 2015, corrugated products shipments were higher while containerboard and corrugated prices and mix were down due to lower export prices and industry published price decreases. During the second quarter of 2016, we successfully completed scheduled maintenance outages at our Tomahawk, Counce, and Wallula mills.
Packaging segment income from operations was $354 million in the first six months of 2016, compared to $336 million in the first six months of 2015. Packaging segment EBITDA excluding special items was $503 million in the first six months of 2016, compared to $489 million in the first six months of 2015. Compared to the first six months of 2015, both containerboard and corrugated products shipments were higher with lower mill outage and energy costs, while containerboard and corrugated prices and mix were down.
Paper segment income from operations was $24 million in the second quarter of 2016, compared to $23 million in the second quarter of 2015. Paper segment EBITDA excluding special items increased to $39 million in the second quarter of 2016, compared to $37 million in the second quarter of 2015. White paper shipments were flat and pulp shipments were lower, compared with last year’s second quarter. White paper prices and mix were unfavorable to last year’s second quarter; however, our mills ran efficiently and effectively managed costs throughout the quarter, leading to strong margin performance.
Paper segment income from operations was $61 million in the first six months of 2016, compared to $59 million in the first six months of 2015. Paper segment EBITDA excluding special items was $90 million in the first six months of 2016, compared to $86 million in the first six months of 2015. White paper shipments were flat and pulp shipments were lower, compared with the first six months of last year. White paper prices and mix were unfavorable; however, fiber and energy costs were lower, leading to increased margins.
Special Items and Earnings per Diluted Share, Excluding Special Items
The second quarters of 2016 and 2015 both included $3 million of pre-tax expense for special items. The special items in the second quarter of 2016 included $2 million for to facilities closure costs related to corrugated manufacturing facilities and a paper distribution center and $1 million related to our withdrawal from a multiemployer pension plan for one of our corrugated products facilities. The three months ended June 30, 2015 included $4 million of Boise acquisition integration-related and other costs and $1.0 million of income for insurance proceeds received related to the DeRidder mill restructuring.
The six months ended June 30, 2016 included $6 million of pre-tax expense for special items, compared with $16 million of pre-tax expense for special items during the same period in 2015. The six months ended June 30, 2016 included $5 million for facilities closure costs related to corrugated manufacturing facilities and a paper distribution center and $1 million related to our withdrawal from a multiemployer pension plan for one of our corrugated products facilities. The six months ended June 30, 2015 included $7 million of Boise acquisition integration-related and other costs and $9 million of expenses related to the DeRidder mill restructuring.
A reconciliation of reported earnings per diluted share to earnings per share, excluding special items, for the three and six months ended June 30, 2016 and 2015 are as follows:

____________

(a) | See "Reconciliations of Non-GAAP Financial Measures to Reported Amounts" in this Management's Discussion and Analysis of Financial Condition and Results of Operations for more information on the special items.

Management excludes special items as it believes these items are not necessarily reflective of the ongoing results of operations of our business. We present these measures because they provide a means to evaluate the performance of our segments and our company on an ongoing basis using the same measures that are used by our management, because these measures assist in providing a meaningful comparison between periods presented and because these measures are frequently used by investors and other interested parties in the evaluation of companies and the performance of their segments. A reconciliation of diluted EPS to diluted EPS excluding special items is included above and the reconciliations of other non-GAAP measures used in this Management's Discussion and Analysis of Financial Condition and Results of Operations, to the most comparable measure reported in accordance with GAAP, are included in Item 2 under "Reconciliations of Non-GAAP Financial Measures to Reported Amounts." Any analysis of non-GAAP financial measures should be done in conjunction with results presented in accordance with GAAP. The non-GAAP measures are not intended to be substitutes for GAAP financial measures and should not be used as such.
Industry and Business Conditions
Trade publications reported that industry-wide corrugated products shipments increased 1.8% during the second quarter of 2016, compared with the same quarter in 2015, and remained essentially flat per workday with one less workday in 2015. Reported industry containerboard production was flat compared with the second quarter of 2015, and reported industry containerboard inventories at the end of the second quarter of 2016 were approximately 2.4 million tons, down 2.6% compared to the same period in 2015. Reported containerboard export shipments were up 1.7% compared to the second quarter of 2015.
The market for communication papers competes heavily with electronic data transmission and document storage alternatives. Increasing shifts to these alternatives have reduced usage of traditional print media and communication papers. Trade publications reported that uncoated freesheet paper shipments were down 2.8% in the second quarter of 2016, compared with the same quarter in 2015. Average prices reported by a trade publication for cut size office papers were lower by $27 per ton, or 2.7%, in the second quarter of 2016, compared with the second quarter of 2015.
Outlook
Looking ahead to the third quarter 2016, we expect higher containerboard, corrugated products and white paper shipments. Paper prices should move higher reflecting continued realization of the announced price increases in first quarter 2016, and our annual outage costs will be lower. We expect a less rich mix in corrugated products and higher prices for recycled fiber, electricity and fuels. Considering these items, we expect third quarter earnings, excluding special items, to be higher than our second quarter earnings. We expect to complete the acquisition of TimBar later in the third quarter, subject to the satisfaction of customary conditions.

Net Sales
Net sales decreased $37 million, or 2.5%, to $1,417 million during the three months ended June 30, 2016, compared with $1,454 million during the same period in 2015.
Packaging. Net sales decreased $17 million, or 1.5%, to $1,125 million, compared with $1,142 million in the second quarter of 2015, primarily due to lower export and domestic containerboard and corrugated products price and mix ($30 million) and lower domestic and export containerboard volume ($4 million), partially offset by increased corrugated products volume ($17 million). Our domestic and export containerboard prices in the second quarter of 2016 decreased 4.9% and 8.6%, respectively, compared with the same quarter last year, due to published price decreases. In the second quarter of 2016, our containerboard outside shipments decreased 8.0%, and corrugated products shipments were up 2.2%, compared with the second quarter of 2015.
Paper. Net sales during the three months ended June 30, 2016 decreased $14 million, or 5.0%, to $267 million, compared with $281 million in the second quarter of 2015. Sales decreased primarily due to lower volume ($13 million) and changes in price and mix ($1 million). White paper prices and mix in the second quarter of 2016 decreased 3.0% compared with
18

the same period last year. In the second quarter of 2016, our white paper shipments increased slightly, which was more than offset by lower pulp shipments (17,000 tons) compared to the second quarter of 2015.
Gross Profit
Gross profit was relatively flat, increasing $2 million during the three months ended June 30, 2016, compared with the same period in 2015. The increase was primarily due to higher corrugated products volumes and lower energy, freight, and fiber, partially offset by lower prices and mix in white paper, containerboard and corrugated products. In the second quarters of 2016 and 2015, there were no significant special items impacting gross profit.
Selling, General, and Administrative Expenses
Selling, general, and administrative expenses were relatively flat, decreasing $1 million during the three months ended June 30, 2016, compared with the same period in 2015. The decrease was due primarily to lower administrative employee costs.
Other Expense, Net
Other expense, net, during the three months ended June 30, 2016 was $5 million, compared with $4 million during the three months ended June 30, 2015. The second quarter of 2016 included $1 million of facilities closure costs, $1 million of asset disposal expense, and $1 million of costs related to our withdrawal from a multiemployer pension plan for one of our corrugated products facilities. The second quarter of 2015 included $4 million of asset disposal expense and $4 million of integration-related and other costs, partially offset by $1 million of insurance proceeds received related to the DeRidder mill restructuring. We discuss these items in more detail in Note 3, Other Expense, Net of the Condensed Notes to Unaudited Quarterly Consolidated Financial Statements in "Part I, Item1. Financial Statements" of this Form 10-Q.
Income from Operations
Income from operations increased $3 million, or 1.5%, during the three months ended June 30, 2016, compared with the same period in 2015. The second quarters of 2016 and 2015 each included $3 million of expense from special items. The special items in the second quarter of 2016 included $2 million related to facilities closure costs related to corrugated manufacturing facilities and a paper distribution center and $1 million related to our withdrawal from a multiemployer pension plan for one of our corrugated products facilities. The three months ended June 30, 2015 included $4 million of Boise acquisition integration-related and other costs and $1 million of income for insurance proceeds received related to the DeRidder mill restructuring. In addition to the net difference resulting from special items of $3 million discussed above, income from operations increased $3 million during the three months ended June 30, 2016, compared with the same period in 2015. The increase was primarily due to increased corrugated products volumes and lower operating costs, partially offset by lower prices and mix in white paper, containerboard and corrugated products.
Packaging. Packaging segment income from operations was relatively flat, decreasing $3 million to $192 million, compared with $195 million during the three months ended June 30, 2015. The decrease in the second quarter of 2016 related primarily to lower domestic containerboard and corrugated products prices and mix ($6 million), lower domestic and export containerboard volume ($6 million), lower export prices ($4 million), higher depreciation and other fixed costs ($3 million), and higher labor costs ($1 million), offset by lower freight costs ($6 million), higher corrugated products volume ($6 million), and lower energy costs ($6 million). Special items included $1 million of facilities closure costs and $1 million related to our withdrawal from a multiemployer pension plan for one of our corrugated products facilities in the second quarter of 2016 and $1 million of income for insurance proceeds received related to the DeRidder mill restructuring and $2 million of integration-related and other costs related to the Boise acquisition for the same period in 2015.
Paper. Paper segment income from operations was relatively flat, increasing $1 million to $24 million, compared with $23 million during the three months ended June 30, 2015. The increase primarily related to lower fiber ($6 million) and energy ($3 million) costs, partially offset by lower white paper prices and mix ($2 million), lower pulp volume ($3 million), and higher mill outage costs ($2 million).
Interest Expense, Net, and Income Taxes
Interest expense, net, remained flat at $22 million in both the three months ended June 30, 2016 and 2015.
19

During the three months ended June 30, 2016, we recorded $62 million of income tax expense, compared with $61 million of expense during the three months ended June 30, 2015. The effective tax rate for the three months ended June 30, 2016 and 2015 was 34.8% and 35.0%, respectively.

Net Sales
Net sales decreased $62 million, or 2.2%, to $2,818 million during the six months ended June 30, 2016, compared with $2,880 million during the same period in 2015.
Packaging. Net sales decreased $21 million, or 0.9%, to $2,221 million, compared with $2,242 million in the six months ended June 30, 2015, primarily due to lower export and domestic containerboard and corrugated products price and mix ($48 million), lower sales due to the divestiture of our Hexacomb operations in Mexico and Europe in 2015 ($11 million), and lower export and domestic containerboard volume ($5 million), partially offset by increased corrugated products volumes ($43 million). Domestic and export containerboard prices in the first six months of 2016 decreased 4.5% and 8.0%, respectively, compared with the same period last year, due to published price decreases. In the first six months of 2016, our containerboard outside shipments decreased 4.7%, and corrugated products shipments were up 2.8%, compared with the first six months of 2015.
Paper. Net sales during the six months ended June 30, 2016 decreased $31 million, or 5.4%, to $547 million, compared with $578 million in the six months ended June 30, 2015. Sales decreased primarily due to lower volume ($26 million) and changes in price and mix ($5 million). White paper prices and mix in the first six months of 2016 decreased 3.0%
20

compared with the same period last year. In the first six months of 2016, our white paper shipments were flat and pulp shipments decreased (27,000 tons) compared with the same period last year.
Gross Profit
Gross profit increased $24 million, or 4.0%, during the six months ended June 30, 2016, compared with the same period in 2015. The increase was primarily due to higher corrugated products volumes and lower energy, fiber, freight, and maintenance costs, partially offset by lower white paper, containerboard and corrugated products prices and mix, and lower pulp volume. In the first six months of 2016 and 2015, gross profit included special items of $1 million for facilities closure costs and $9 million for DeRidder mill restructuring charges, respectively, most of which related to incremental depreciation expense associated with changing the estimated useful lives of mill assets.
Selling, General, and Administrative Expenses
Selling, general, and administrative expenses decreased $4 million, or 1.7%, during the six months ended June 30, 2016, compared with the same period in 2015. The decrease was due primarily to lower administrative employee costs from the headcount reductions related to the Boise integration.
Other Expense, Net
Other expense, net, during the six months ended June 30, 2016 was $9 million, compared with $7 million during the six months ended June 30, 2015. The six months ended June 30, 2016 included $3 million of facilities closure costs, $3 million of asset disposal expense, and $1 million of costs related to our withdrawal from a multiemployer pension plan for one of our corrugated products facilities. The six months ended June 30, 2015 included $7 million of integration-related and other costs relating to the Boise acquisition and $5 million of asset disposal expense, partially offset by $4 million of income from a refundable state tax credit received related to our investments and the jobs retained at DeRidder. We discuss these items in more detail in Note 3, Other Expense, Net of the Condensed Notes to Unaudited Quarterly Consolidated Financial Statements in "Part I, Item1. Financial Statements" of this Form 10-Q.
Income from Operations
Income from operations increased $26 million, or 7.3%, during the six months ended June 30, 2016, compared with the same period in 2015. The first six months of 2016 included $6 million of expense from special items, compared with $16 million of expense from special items in the first six months of 2015. Special items for the six months ended June 30, 2016 included $4 million related to facilities closure costs related to corrugated manufacturing facilities and a paper distribution center and $1 million related to our withdrawal from a multiemployer pension plan for one of our corrugated products facilities. The six months ended June 30, 2015 included $9 million of charges related to restructuring the DeRidder mill and $7 million of Boise acquisition integration-related and other costs. In addition to the net difference resulting from special items of $6 million discussed above, income from operations increased $16 million during the six months ended June 30, 2016, compared with the same period in 2015. The increase was primarily due to increased corrugated products volumes and lower operating costs, partially offset by lower prices and mix in white paper, containerboard and corrugated products.
Packaging. Packaging segment income from operations increased $18 million, or 5.4%, to $354 million, compared with $336 million during the six months ended June 30, 2015. The increase in the first six months of 2016 related primarily to lower mill outage ($13 million), freight ($12 million), and energy ($10 million) costs, higher volume ($5 million), and lower expense for special items ($8 million) compared to the same period in 2015, offset partially by lower containerboard and corrugated products prices and mix ($19 million), depreciation ($4 million), and labor ($4 million) costs, and a state incentive received in 2015 related to investments at our DeRidder mill ($4 million). Special items included $3 million of facilities closure costs and $1 million related to our withdrawal from a multiemployer pension plan for one of our corrugated products facilities in the first six months of 2016 and $9 million of DeRidder restructuring charges and $3 million of integration-related and other costs relating to the Boise acquisition for the same period in 2015.
Paper. Paper segment income from operations was relatively flat, increasing $2 million to $61 million, compared to the six months ended June 30, 2015. Costs were lower for fiber ($11 million) and energy ($8 million) in the first half of 2016 compared to the same period in 2015, partially offset by lower white paper prices and mix ($7 million), lower pulp volume ($6 million), and higher mill outage ($2 million) costs and other costs that were individually insignificant.
21

Interest Expense, Net, and Income Taxes
Interest expense, net, was $44 million during the six months ended June 30, 2016, compared with $42 million during the six months ended June 30, 2015. The increase in interest expense was primarily due to lower interest rebate income related to one of our term loans recorded in the first quarter of 2016 compared to the first quarter of 2015.
During the six months ended June 30, 2016, we recorded $117 million of income tax expense, compared with $108 million of expense during the six months ended June 30, 2015. The effective tax rate for the six months ended June 30, 2016 and 2015 was 34.8% and 34.6%, respectively.
Liquidity and Capital Resources
Sources and Uses of Cash
Our primary sources of liquidity are net cash provided by operating activities and available borrowing capacity under our revolving credit facility. At June 30, 2016 we had $214 million of cash and $326 million of unused borrowing capacity under the revolving credit facility, net of letters of credit. Currently, our primary uses of cash are for operations, capital expenditures, debt service (including voluntary payments of debt), repurchases of common stock, and declared common stock dividends. We believe that net cash generated from operating activities, cash on hand, available borrowings under our revolving credit facility, and available capital through access to capital markets will be adequate to meet our liquidity and capital requirements, including payments of any declared common stock dividends, for the foreseeable future. As our debt or credit facilities become due, we will need to repay, extend, or replace such facilities. Our ability to do so will be subject to future economic conditions and financial, business, and other factors, many of which are beyond our control.
Below is a summary table of our cash flows, followed by a discussion of our sources and uses of cash through operating activities, investing activities, and financing activities (dollars in millions):

| Six Months Ended June 30 |  |
| 2016 |  | 2015 |  | Change
Net cash provided by (used for): |  |  |  |  |
Operating activities | $ | 371 |  |  | $ | 305 |  |  | $ | 66 |
Investing activities | (128 | ) |  | (124 | ) |  | (4 | )
Financing activities | (214 | ) |  | (142 | ) |  | (72 | )
Net increase in cash and cash equivalents | $ | 29 |  |  | $ | 39 |  |  | $ | (10 | )

Operating Activities
During the six months ended June 30, 2016, net cash provided by operating activities was $371 million, compared with $305 million in the same period in 2015, an increase of $66 million. Cash from operations excluding changes in cash used for operating assets and liabilities increased $8 million, primarily due to higher income as discussed above. The remaining $58 million increase from changes in cash used for operating assets and liabilities was primarily due to the following: (a) a smaller increase in our accounts receivable in the first six months of 2016 related to differences in the timing of collections of receivables, primarily in the Paper segment and (b) an increase in taxes payable resulting from higher taxable income levels in the first six months of 2016 compared to the same quarter in the prior period. Cash requirements for operating activities are subject to PCA’s operating needs and the timing of collection of receivables and payments of payables and expenses.
Investing Activities
Net cash used for investing activities during the six months ended June 30, 2016 decreased $4 million, to $128 million, compared with $124 million during the same period in 2015. We spent $122 million for capital investments during the six months ended June 30, 2016, compared with $142 million during the same period in 2015. We received $23.0 million of cash proceeds for the sale of our Hexacomb corrugated manufacturing operations in Mexico and Europe during the first six months of 2015.
22

We expect capital investments to be between $250 million and $285 million in 2016, excluding any acquisitions or other strategic activities. These expenditures could increase or decrease as a result of a number of factors, including our financial results, future economic conditions, and our regulatory compliance requirements. We currently estimate capital expenditures to comply with Boiler MACT regulations in 2016 of up to $3 million, and we expect other environmental capital expenditures of about $5 million in 2016. Our estimated environmental expenditures could vary significantly depending upon the enactment of new environmental laws and regulations, including those related to greenhouse gas emissions and industrial boilers. For additional information, see "Environmental Matters" in "Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" of our 2015 Annual Report on Form 10-K.
Financing Activities
During the six months ended June 30, 2016, we used $214 million for financing activities, compared with $142 million during the same period in 2015. The increase in cash used for financing activities primarily related to an increase in share repurchases and a higher dividend payment. In the first six months of 2016, we paid $105 million of dividends compared with $93 million of dividends paid during the first six months of 2015. On February 26, 2015 PCA's Board of Directors increased the regular quarterly cash dividend to $0.55 per share from the previous $0.40 per share dividend, beginning with the dividend paid on April 15, 2015. During the six months ended June 30, 2016, we paid $100 million to repurchase 1,987,187 shares of common stock, compared with $43 million of share repurchases in the same period in 2015. We also withheld shares from vesting equity awards to cover employee tax liabilities of $10 million in the first six months of 2016, compared with $7 million in the same period of 2015.
As PCA completed share repurchases under its prior authorization, on February 25, 2016 PCA announced that its Board of Directors authorized the repurchase of an additional $200 million of the Company’s outstanding common stock. Repurchases may be made from time to time in open market or privately negotiated transactions in accordance with applicable securities regulations. The timing and amount of repurchases will be determined by the Company in its discretion based on factors such as PCA’s stock price and market and business conditions.
For more information about our debt, see Note 10, Debt, of the Notes to Consolidated Financial Statements in "Part II, Item 8. Financial Statements and Supplementary Data" of our 2015 Annual Report on Form 10-K.
Contractual Obligations
On July 1, 2016 we entered into a definitive agreement to acquire substantially all of the assets of TimBar Corporation for a cash purchase price of $386 million. Closing is subject to certain customary conditions and is expected in the third quarter of 2016.
There have been no other material changes to the contractual obligations table disclosed in Item 7. "Management’s Discussion and Analysis of Financial Condition and Results of Operations" of our 2015 Annual Report on Form 10-K.

Reconciliations of Non-GAAP Financial Measures to Reported Amounts
Income from operations excluding special items, net income excluding special items, EBITDA, and EBITDA excluding special items are non-GAAP financial measures. Management excludes special items as it believes that these items are not necessarily reflective of the ongoing operations of our business. These measures are presented because they provide a means to evaluate the performance of our segments and our Company on an ongoing basis using the same measures that are used by our management, because these measures assist in providing a meaningful comparison between periods and because these measures are frequently used by investors and other interested parties in the evaluation of companies and the performance of their segments. Any analysis of non-GAAP financial measures should be done in conjunction with results presented in accordance with GAAP. The non-GAAP measures are not intended to be substitutes for GAAP financial measures and should not be used as such. Reconciliations of the non-GAAP measures to the most comparable measure reported in accordance with GAAP for the three and six months ended June 30, 2016 and 2015 follow (dollars in millions):

Market Risk and Risk Management Policies
PCA is exposed to the impact of interest rate changes and changes in the market value of its financial instruments. We periodically enter into derivatives to minimize these risks, but not for trading purposes. At June 30, 2016 we had no derivative instruments outstanding. For a discussion of derivatives and hedging activities, see Note 14, Derivative Instruments and Hedging Activities, of the Notes to Consolidated Financial Statements in "Part II, Item 8. Financial Statements and Supplementary Data" of our 2015 Annual Report on Form 10-K.
The interest rates on approximately 70% of PCA’s debt are fixed. A one percent increase in interest rates related to variable-rate debt would have resulted in an increase in interest expense and a corresponding decrease in income before taxes of approximately $7 million annually.
Off-Balance-Sheet Activities
The Company does not have any off-balance sheet arrangements as of June 30, 2016.

Environmental Matters
There have been no material changes to the disclosure set forth in Item 7. "Management’s Discussion and Analysis of Financial Condition and Results of Operations - Environmental Matters" filed with our 2015 Annual Report on Form 10-K.
Critical Accounting Policies and Estimates
Management’s discussion and analysis of financial condition and results of operations are based upon the Company’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an ongoing basis, PCA evaluates its estimates, including those related to pensions and other postretirement benefits, goodwill and intangible assets, long-lived asset impairment, and income taxes, among others. PCA bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
PCA has included in its 2015 Annual Report on Form 10-K a discussion of its critical accounting policies and estimates which require management's most difficult, subjective, or complex judgments used in the preparation of its consolidated financial statements. PCA has not had any changes to these critical accounting estimates during the first six months of 2016.
New and Recently Adopted Accounting Standards
For a listing of our new and recently adopted accounting standards, see Note 16, New and Recently Adopted Accounting Standards, of the Condensed Notes to Unaudited Quarterly Consolidated Financial Statements in "Part I, Item 1. Financial Statements" of this Form 10-Q.
Forward-Looking Statements
Some of the statements in this Quarterly Report on Form 10-Q, and in particular, statements found in this Management’s Discussion and Analysis of Financial Condition and Results of Operations, that are not historical in nature are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are often identified by the words "will," "should," "anticipate," "believe," "expect," "intend," "estimate," "hope," or similar expressions. These statements reflect management’s current views with respect to future events and are subject to risks and uncertainties. There are important factors that could cause actual results to differ materially from those in forward-looking statements, many of which are beyond our control. These factors, risks and uncertainties include the following:

• | the impact of general economic conditions;

• | the impact of acquired businesses and risks and uncertainties regarding operation, expected benefits and integration of such businesses;

• | containerboard, corrugated products, and white paper general industry conditions, including competition, product demand, product pricing, and input costs;

• | fluctuations in wood fiber and recycled fiber costs;

• | fluctuations in purchased energy costs;

• | the possibility of unplanned outages or interruptions at our principal facilities; and

• | legislative or regulatory actions or requirements, particularly concerning environmental or tax matters.

Our actual results, performance or achievement could differ materially from those expressed in, or implied by, these forward-looking statements, and accordingly, we can give no assurances that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do occur, what impact they will have on our results of operations or financial condition. Given these uncertainties, investors are cautioned not to place undue reliance on these forward-looking statements. We expressly disclaim any obligation to publicly revise any forward-looking statements that have been made to reflect the occurrence of events after the date hereof. For a discussion of other factors, risks and uncertainties that may affect our business, see Item 1A. Risk Factors included in our Annual Report on Form 10-K for the year ended December 31, 2015.

For a discussion of market risks related to PCA, see Part I, Item 2, "Management’s Discussion and Analysis of Financial Condition and Results of Operations - Market Risk and Risk Management Policies" in this Quarterly Report on Form 10-Q.

Item 4. | 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.
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 June 30, 2016. 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. 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 June 30, 2016.
During the quarter ended June 30, 2016 there were no changes in internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, PCA’s internal control over financial reporting.
