Notes to Condensed Consolidated Financial Statements
(Unaudited)
March 31, 2011

1.   Basis of Presentation

The condensed consolidated financial statements as of March 31, 2011 and 2010 of Packaging Corporation of America (“PCA” or the “Company”) and for the three month periods then ended 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 SECRegulation 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 period ended March 31, 2011 are not necessarily indicative of the results that may be expected for the year ending December 31, 2011. These condensed consolidated financial statements should be read in conjunction with PCA’s Annual Report onForm 10-K for the year ended December 31, 2010.

2.   Summary of Accounting Policies

Basis of Consolidation

The accompanying condensed consolidated financial statements of PCA include all majority-owned subsidiaries. All intercompany transactions have been eliminated. The Company has one joint venture that is accounted for under the equity method.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts in the financial statements and the accompanying notes. Actual results could differ from those estimates.

Revenue Recognition

The Company recognizes revenue as title to the products is transferred to customers. Shipping and handling billings to a customer are included in net sales. Shipping and handling costs are included in cost of sales. In addition, the Company offers volume rebates to certain of its customers. The total cost of these programs is estimated and accrued as a reduction to net sales at the time of the respective sale.

Segment Information

PCA is engaged in one line of business: the integrated manufacture and sale of packaging materials, boxes and containers for industrial and consumer markets. No single customer accounts for more than 10% of total net sales.

Recent Accounting Pronouncements

In December 2010, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”)2010-28, “Intangibles — Goodwill and Other (Topic 350) — When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts.” This ASU modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For such reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. ASU2010-28 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. The adoption of this guidance on January 1, 2011 did not have any impact on the Company’s financial position, results of operations or cash flows.

2.   Summary of Accounting Policies (Continued)

In January 2010, the FASB issued ASU2010-06, “Fair Value Measurements and Disclosures (Topic 820) — Improving Disclosures about Fair Value Measurements.” This ASU requires new disclosures and clarifies existing disclosure requirements about fair value measurement as set forth in Accounting Standards Codification (“ASC”) 820. ASU2010-06 amends ASC 820 to now require: (1) a reporting entity should disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers; and (2) in the reconciliation for fair value measurements using significant unobservable inputs, a reporting entity should present separately information about purchases, sales, issuances, and settlements. In addition,ASU 2010-06 clarifies the requirements of existing disclosures. ASU2010-06 is effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances, and settlements in the roll forward of activity in Level 3 fair value measurements. Those disclosures are effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. As of January 1, 2011, the Company has adopted all disclosure provisions of this guidance. See Note 12 for additional information.

3.   Earnings Per Share

The following table sets forth the computation of basic and diluted income per common share for the periods presented.

	Three Months Ended
	March 31,
	2011		2010
(In thousands, except per share data)
Numerator:
Net income	$	37,417	$	19,194
Denominator:
Basic common shares outstanding		100,741		101,928
Effect of dilutive securities:
Stock options		332		255
Unvested restricted stock		836		693
Dilutive common shares outstanding		101,909		102,876
Basic income per common share	$	0.37	$	0.19
Diluted income per common share	$	0.37	$	0.19

Options to purchase 0.6 million shares for the three month period ended March 31, 2010, were not included in the computation of diluted common shares outstanding as their exercise price exceeded the average market price of the Company’s common stock for the respective reporting period. All outstanding options to purchase shares for the three months ended March 31, 2011 were included in the computation of diluted common shares outstanding.

(In thousands)
Net income	$	37,417		$	19,194

Unrealized gains (losses) on foreign currency exchange contracts		163			(811	)
Comprehensive income	$	43,769		$	18,816

5.   Stock-Based Compensation

In October 1999, the Company adopted a long-term equity incentive plan, which provides for grants of stock options, stock appreciation rights, restricted stock and performance awards to directors, officers and employees of PCA, as well as others who engage in services for PCA. Option awards granted to directors, officers and employees have contractual lives of seven or ten years. Options granted to officers and employees vest ratably over a three-year period, and options granted to directors vest immediately. Restricted stock awards granted to employees generally vest at the end of a four-year period, and restricted stock awards granted to directors vest at the end of a six-month period. The plan, which will terminate on October 19, 2014, provides for the issuance of up to 8,550,000 shares of common stock over the life of the plan. As of March 31, 2011, options and restricted stock of 7,288,381 shares have been granted, net of forfeitures. Forfeitures are added back to the pool of shares of common stock available to be granted at a future date.

Compensation expense for both stock options, which were fully vested at June 30, 2010, and restricted stock recognized in the condensed consolidated statements of income for the three-month periods ended March 31, 2011 and 2010 was as follows:

	Three Months Ended
	March 31,
	2011			2010
(In thousands)
Stock options	$	—		$	157
Restricted stock		1,750			1,079
Impact on income before income taxes		1,750			1,236
Income tax benefit		(681	)		(481	)
Impact on net income	$	1,069		$	755

The Company uses the Black-Scholes-Merton option-pricing model to estimate the fair value of each option grant as of the date of grant. Expected volatilities are based on historical volatility of the Company’s common stock. The expected life of the option is estimated using historical data pertaining to option exercises and employee terminations. Separate groups of employees that have similar historical exercise behavior are considered separately for estimating the expected life. The risk-free interest rate is based on U.S. Treasury yields in effect at the time of

5.   Stock-Based Compensation (Continued)

grant. The fair value of restricted stock is determined based on the closing price of the Company’s common stock on the grant date. There were no option grants during the first three months of 2011.

A summary of the Company’s stock option activity and related information follows:

						Weighted-
				Weighted-		Average
				Average		Remaining		Aggregate
				Exercise		Contractual		Intrinsic
	Options			Price		Term (years)		Value
								(In thousands)
Outstanding at December 31, 2010		1,568,384		$	21.38
Exercised		(161,992	)		19.78
Outstanding and exercisable at March 31, 2011		1,406,392		$	21.56		2.2	$	10,303

The total intrinsic value of options exercised during the three months ended March 31, 2011 and 2010 was $1.5 million and $0.8 million, respectively. As of March 31, 2011, there is no unrecognized compensation cost related to stock option awards granted under the Company’s equity incentive plan as all outstanding awards have vested.

A summary of the Company’s restricted stock activity follows:

	2011						2010
				Fair Market						Fair Market
				Value at						Value at
				Date of						Date of
(Dollars in thousands)	Shares			Grant			Shares			Grant
Restricted stock at January 1		1,478,000		$	30,600			1,235,505		$	24,718
Granted		200,000			5,796			—			—
Vested		(1,970	)		(41	)		(113,580	)		(2,277	)
Cancellations		(1,150	)		(24	)		(7,320	)		(145	)
Restricted stock at March 31		1,674,880		$	36,331			1,114,605		$	22,296

The Company generally recognizes compensation expense associated with restricted stock awards ratably over their vesting periods. As PCA’s Board of Directors has the ability to accelerate vesting of restricted stock upon an employee’s retirement, the Company accelerates the recognition of compensation expense for certain employees approaching normal retirement age. As of March 31, 2011, there was $19.3 million of total unrecognized compensation costs related to the above restricted stock awards. The Company expects to recognize the cost of these stock awards over a weighted-average period of 2.7 years.

6.   Inventories

The components of inventories are as follows:

	March 31,			December 31,
	2011			2010
(In thousands)				(Audited)
Raw materials	$	120,572		$	126,401
Work in process		7,743			6,395
Finished goods		72,585			73,710
Supplies and materials		102,647			102,720
Inventories at FIFO or average cost		303,547			309,226
Excess of FIFO or average cost over LIFO cost		(69,631	)		(68,084	)
Inventories, net	$	233,916		$	241,142

An actual valuation of inventory under the LIFO method is made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations must necessarily be based on management’s estimates of expected year-end inventory levels and costs. Because these are subject to many factors beyond management’s control, interim results are subject to the final year-end LIFO inventory valuation.

7.   Other Intangible Assets

The components of other intangible assets are as follows:

			As of March 31, 2011				As of December 31, 2010
	Weighted		Gross				Gross
	Average		Carrying		Accumulated		Carrying		Accumulated
	Remaining Life		Amount		Amortization		Amount		Amortization
(In thousands)							(Audited)
Customer lists and relations		31.7 years	$	17,441	$	6,670	$	17,441	$	6,466

8.   Employee Benefit Plans and Other Postretirement Benefits

For the three months ended March 31, 2011 and 2010, net pension costs were comprised of the following:

	Three Months
	Ended
	March 31,
	2011			2010
(In thousands)
Components of Net Pension Costs
Service cost for benefits earned during the year	$	4,952		$	4,579
Interest cost on accumulated benefit obligation		3,368			3,023
Expected return on assets		(3,385	)		(2,802	)
Net amortization of unrecognized amounts		1,548			1,483
Net pension costs	$	6,483		$	6,283

The Company 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). However, from time to time the Company may make discretionary contributions in excess of the required minimum

amounts. The Company expects to contribute $22.1 million to the pension plans in 2011, of which $2.1 million has been contributed through March 31, 2011.

For the three months ended March 31, 2011 and 2010, net postretirement costs were comprised of the following:

	Three Months
	Ended
	March 31,
	2011		2010

Components of Net Postretirement Costs
Service cost for benefits earned during the year	$	400	$	350
Interest cost on accumulated benefit obligation		297		283
Net amortization of unrecognized amounts		8		(19	)
Net postretirement costs	$	705	$	614

9.   Transfers of Financial Assets

PCA has an on-balance sheet securitization program for its trade accounts receivable that is accounted for as a secured borrowing under ASC 860, “Transfers and Servicing.” To effectuate this program, the Company formed a wholly owned, limited-purpose subsidiary, Packaging Credit Company, LLC (“PCC”), which in turn formed a wholly owned, bankruptcy-remote, special-purpose subsidiary, Packaging Receivables Company, LLC (“PRC”), for the purpose of acquiring receivables from PCC. Both of these entities are included in the consolidated financial statements of the Company. Under this program, PCC purchases on an ongoing basis substantially all of the receivables of the Company and sells such receivables to PRC. PRC and lenders established a $150.0 million receivables-backed revolving credit facility (“Receivables Credit Facility”) through which PRC obtains funds to purchase receivables from PCC. The receivables purchased by PRC are solely the property of PRC. In the event of liquidation of PRC, the creditors of PRC would be entitled to satisfy their claims from PRC’s assets prior to any distribution to PCC or the Company. Credit available under the receivables credit facility is on a borrowing-base formula. As a result, the full amount of the facility may not be available at all times. On March 1, 2011, PCA renewed the facility, which was scheduled to expire on March 1, 2011, to February 28, 2012. At March 31, 2011, $109.0 million was outstanding and included in “Short-term debt and current maturities of long-term debt” on the condensed consolidated balance sheet. Substantially all accounts receivable at March 31, 2011 have been sold to PRC and are included in “Accounts receivable, net of allowance for doubtful accounts and customer deductions” on the condensed consolidated balance sheet.

10.   Derivative Instruments and Hedging Activities

The Company records its derivatives in accordance with ASC 815, “Derivatives and Hedging.” The guidance requires the Company to recognize derivative instruments as either assets or liabilities in 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 in 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) (“OCI”) and is subsequently recognized in earnings when the hedged exposure affects earnings. The ineffective portion of the gain or loss is recognized in earnings.

10.   Derivative Instruments and Hedging Activities (Continued)

Hedging Strategy

PCA is exposed to certain risks relating to its ongoing operations. When appropriate, the Company uses derivatives as a risk management tool to mitigate the potential impact of certain market risks. The primary risks managed by using derivative financial instruments are interest rate and foreign currency exchange rate risks. PCA does not enter into derivative financial instruments for trading or speculative purposes.

Interest Rate Risk

The Company has historically used treasury lock derivative instruments to manage interest costs and the risk associated with changing interest rates. On June 12, 2003 and January 17, 2008, in connection with contemplated issuances of ten-year debt securities, PCA entered into interest rate protection agreements with counterparties to protect against increases in the ten-year U.S. Treasury Note rate. These treasury rates served as references in determining the interest rates applicable to the debt securities the Company issued in July 2003 and March 2008, respectively. As a result of changes in the interest rates on those treasury securities between the time PCA entered into the agreements and the time PCA priced and issued the debt securities, the Company: (1) received a payment of $22.8 million from the counterparty upon settlement of the 2003 interest rate protection agreement on July 21, 2003; and (2) made a payment of $4.4 million to the counterparty upon settlement of the 2008 interest rate protection agreement on March 25, 2008. The Company recorded the settlements in accumulated other comprehensive income (loss), which are amortized over the terms of the respective notes.

On May 25, 2010, in connection with a contemplated issuance of ten-year debt securities to eventually refinance PCA’s currently outstanding $400.0 million of senior notes that mature in 2013, PCA entered into interest rate protection agreements with counterparties to protect against increases in the ten-year U.S. Treasury Note rate. The treasury rate will serve as a reference in determining the interest rate applicable to the new debt securities the Company expects to issue in the future. The interest rate protection agreements were properly documented and designated as cash flow hedges at inception. On February 4, 2011, PCA settled the treasury locks and received a payment of $9.9 million. The settlement was recorded in accumulated other comprehensive income (loss) and will be amortized over the terms of the respective notes once issued. At March 31, 2011, the Company did not have any interest rate protection agreements outstanding.

Foreign Currency Exchange Rate Risk

In connection with the energy optimization projects at its Valdosta, Georgia mill and Counce, Tennessee mill, the Company entered into foreign currency forward contracts on July 27, 2010 and September 30, 2010 to hedge its exposure to forecasted purchases of machinery and equipment denominated in foreign currencies. The foreign currency forward contracts were properly documented and designated as cash flow hedges at inception. At March 31, 2011, the Company had a notional value of $4.5 million in foreign currency exchange contracts outstanding that are expected to settle by the end of the third quarter of 2011.

Counterparty Credit Risk

The Company is exposed to credit risk in the event of non-performance by counterparties to these derivative financial instruments. The amount of counterparty credit exposure is the unrealized gains, if any, on such derivative contracts. To minimize credit risk, the Company only enters into these types of transactions with investment grade counterparties. On a quarterly basis, the Company evaluates each hedge’s net position relative to the counterparty’s ability to cover its position. Although no assurances can be given, the Company does not expect any of the counterparties to these derivative financial instruments to fail to meet its obligations.

Derivative Instruments

The fair value of the foreign currency forward contracts at March 31, 2011 was $0.3 million, which is included in “Prepaid expenses and other current assets” on the Company’s condensed consolidated balance sheet at March 31, 2011.

The impact of derivative instruments on the condensed consolidated statements of income and accumulated OCI is as follows:

	Amount of Net Gain
	(Loss) Recognized in
	Accumulated OCI
	(Effective Portion)

The amount of gain recognized from accumulated OCI into income is associated with settlements of treasury locks in 2003 and 2008. The net amount of settlement gains or losses on derivative instruments included in accumulated OCI to be realized during the next 12 months is a net gain of $1.8 million ($1.2 million after tax) at March 31, 2011. Mark to market gains and losses on derivative instruments included in accumulated OCI will be reclassified into earnings in the same periods during which the hedged transactions affect earnings. There were no ineffective portions of these contracts during the period.

The fair value of cash and cash equivalents approximates its carrying amounts due to the short-term nature of these financial instruments.

The fair value of the receivables credit facility approximates its carrying amount due to the variable interest-rate feature of the instrument. The fair values of the senior notes are based on quoted market prices. The fair value of the capital lease obligations was estimated to not be materially different from the carrying amount.

12.   Fair Value Measurements

The following presents information about PCA’s assets and liabilities measured at fair value and the valuation techniques used to determine those fair values. The inputs used in the determination of fair values are categorized according to the fair value hierarchy as being Level 1, Level 2 or Level 3 in accordance with ASC 820, “Fair Value Measurements and Disclosures.” The valuation techniques are as follows:

(a) Market approach — prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities

(b) Cost approach — amount that would be required to replace the service capacity of an asset (replacement cost)

(c) Income approach — techniques to convert future amounts to a single present amount based on market expectations (including present value techniques, option-pricing and excess earnings models)

Assets and liabilities measured at fair value on a recurring basis are as follows:

	As of March 31, 2011

12.   Fair Value Measurements (Continued)

The money market funds PCA invests in include funds comprised of U.S. Treasury obligations or backed by U.S. Treasury obligations. The Company measures the fair value of money market funds based on quoted prices in active markets for identical assets.

The Company calculates the fair value of its foreign currency forward contracts using quoted currency spot rates plus or minus forward points to calculate forward rates.

There were no changes in the Company’s valuation techniques used to measure fair values on a recurring basis as a result of adopting ASC 820. PCA had no assets or liabilities that were measured on a nonrecurring basis.

13.   Environmental Liabilities

The potential costs for various environmental matters are uncertain due to such factors as the unknown magnitude of possible cleanup costs, the complexity and evolving nature of governmental laws and regulations and their interpretations, and the timing, varying costs and effectiveness of alternative cleanup technologies. From 1994 through March 31, 2011, remediation costs at PCA’s mills and corrugated plants totaled approximately $3.2 million. As of March 31, 2011, the Company maintained an environmental reserve of $10.0 million relating toon-site landfills and surface impoundments as well as ongoing and anticipated remedial projects. Liabilities recorded for environmental contingencies are estimates of the probable costs based upon available information and assumptions. Because of these uncertainties, PCA’s estimates may change. As of the date of this filing, the Company believes that it is not reasonably possible that future environmental expenditures for remediation costs and asset retirement obligations above the $10.0 million accrued as of March 31, 2011, will have a material impact on its financial condition, results of operations, or cash flows.

14.   Stock Repurchase Program

On October 17, 2007, PCA announced that its Board of Directors authorized a $150.0 million common stock repurchase program. There is no expiration date for the common stock repurchase program. Through March 31, 2011, the Company repurchased 6,177,357 shares of common stock, with 618,236 shares repurchased for $17.2 million, or $27.88 per share, during the first quarter of 2011. Of these shares, 3,300 shares were purchased for $0.1 million during the last several days of March and were subsequently settled and retired in April. All of the remaining shares purchased during the first quarter were retired prior to March 31, 2011. Additionally, 75,000 shares purchased for $2.0 million during the last several days in December 2010 settled and retired in January 2011. As of March 31, 2011, $6.9 million of the $150.0 million authorization remained available for repurchase of the Company’s common stock.

On February 22, 2011, PCA announced that its Board of Directors had authorized the repurchase of an additional $100.0 million of the Company’s outstanding common stock, which remains available as of March 31, 2011, for repurchase of the Company’s common stock.

15.   Alternative Energy Tax Credits

The Company generated black liquor as a by-product of its pulp manufacturing process and used it in a mixture with diesel fuel during 2009 to produce energy at its Counce, Tennessee, Valdosta, Georgia, and Tomahawk, Wisconsin mills. Through December 31, 2009, the U.S. Internal Revenue Code provided a $0.50 per gallon refundable tax credit for taxpayers who used alternative fuels in their trade or business. During the first quarter of 2010, the IRS released a memorandum which provided clarification about the calculation of the alternative fuel mixture credit for black liquor. As a result, during the first quarter of 2010 the Company released a reserve of $9.2 million that was established in 2009 due to the ambiguity in the calculation of the credit. This reserve release

15

March 31, 2011

15.   Alternative Energy Tax Credits (Continued)

resulted in additional income of $9.2 million, which was recorded in alternative fuel mixture tax credits on the income statement in the first quarter of 2010.

The laws governing the taxability of the alternative fuel mixture credit are not completely defined. The IRS has not issued definitive guidance regarding such taxability. PCA believes that the manner in which the credit was claimed will not subject the Company to federal or state income taxes on such benefits. If it is determined that any of the alternative fuel mixture credits are subject to taxation, PCA will be required to pay those taxes and take a corresponding charge to its income.

In an IRS memorandum released during the second quarter of 2010, the IRS concluded that black liquor also qualifies for the taxable cellulosic biofuel producer credit of $1.01 per gallon of biofuel produced in 2009. In a subsequent memorandum, the IRS concluded that a black liquor producer may claim the alternative fuel mixture credit and the cellulosic biofuel producer credit in the same taxable year for different volumes of black liquor (the same gallon of fuel cannot receive both credits but can be claimed as either alternative fuel mixture credit or the cellulosic biofuel producer credit). PCA received the required cellulosic biofuel producer registration code in September 2010.

Based upon both the IRS memoranda and guidance regarding the cellulosic biofuel producer credit, the Company analyzed the additional potential benefits from claiming the cellulosic biofuel producer credit for 2009 instead of the alternative fuel mixture credit, or claiming a combination of the two credits for 2009. For the gallons of alternative fuels produced in 2009, PCA claimed about two-thirds of the gallons as cellulosic biofuel producer credits and about one-third of the gallons as alternative fuel mixture credits, resulting in additional income of $33.4 million recorded during the third quarter of 2010.

During the fourth quarter of 2010 the Company determined that its proprietary biofuel process at the Filer City, Michigan mill would likely qualify for the 2009 cellulosic biofuel producer credit. The Company amended the 2009 federal return in December 2010 to claim these gallons, resulting in $107.0 million of cellulosic biofuel producer credits. Due to the unique and proprietary nature of the Filer City mill process, IRS guidelines do not specifically address the process and uncertainty exists. As a result, the Company increased the reserve for uncertain tax positions under ASC 740 by $102.0 million, which resulted in a net benefit of $5.0 million recorded during the fourth quarter of 2010. During the first quarter of 2011, the Company received notification that the IRS will begin its review of the cellulosic biofuel producer tax credits claimed in the 2009 federal income tax return.

The amount of credits that the Company can apply against future federal taxes owed will be dependent upon the timing and amount of PCA’s future taxable income. As of March 31, 2011, including the reserve for uncertain tax positions, PCA has as much as $206.1 million of tax credits (of which $200.3 million is related to cellulosic biofuel tax credits and $5.8 million related to alternative fuel mixture credits ) to be used to offset future tax payments. The cellulosic biofuel producer credit carryforward must be utilized to offset federal taxes owed by December 31, 2015, at which time the credit carryforward expires. A valuation allowance was not recorded against the deferred tax asset for this credit carryforward since the Company believes the credit can be fully utilized before expiration. If it is determined that any of the credit carryforward will become subject to expiration, PCA will reduce the deferred tax asset and record a corresponding charge to income.

16.   Legal Proceedings

During September and October 2010, PCA and eight other U.S. and Canadian containerboard producers were named as defendants in five purported class action lawsuits filed in the United States District Court for the Northern District of Illinois, alleging violations of the Sherman Act. The lawsuits have been consolidated in a single complaint under the captionKleen Products LLC v Packaging Corp. of America et al.The consolidated complaint

16

Packaging Corporation of America

16.   Legal Proceedings (Continued)

alleges that the defendants conspired to limit the supply of containerboard, and that the purpose and effect of the alleged conspiracy was to artificially increase prices of containerboard products during the period of August 2005 to the time of filing of the complaints. The complaint was filed as a purported class action suit on behalf of all purchasers of containerboard products during such period. The complaint seeks treble damages and costs, including attorney’s fees. The defendants’ motions to dismiss the complaint were denied by the court in April 2011. PCA believes the allegations are without merit and will defend this lawsuit vigorously. However, as the lawsuit is in preliminary stages, PCA is unable to predict the ultimate outcome or estimate a range of reasonably possible losses.

17.   Subsequent Events

The Company has disclosed the following subsequent events in accordance with ASC 855, Subsequent Events.” Subsequent events have been evaluated through the filing date of thisForm 10-Q.

•  On April 4, 2011, the Company’s Valdosta, Georgia mill had a fire that was confined to the turbine generator room. There was no damage to major equipment or other areas of the mill. PCA will be filing an insurance claim in the second quarter of 2011 for the total cost of the fire, including asset write-offs, repair costs and production losses, which are subject to a $3.0 million deductible.

•  On April 14, 2011, the Company acquired Field Packaging Group, a corrugated products manufacturer, located in Chicago, Illinois. Sales and total assets of the acquisition were not material to the Company’s overall sales and total assets prior to the acquisition. Operating results of the acquisition subsequent to April 14, 2011 will be included in the Company’s 2011 operating results. The Company is currently allocating the purchase price to the assets acquired and liabilities assumed.

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

Overview

Packaging Corporation of America, or PCA, is the fifth largest producer of containerboard and corrugated products in the United States, based on production capacity. We produce a wide variety of corrugated products ranging from basic corrugated shipping containers to specialized packaging, such as wax-coated boxes for the agriculture industry. We also have multi-color printing capabilities to make high-impact graphics boxes and displays that offer our customers more attractive packaging. Our operating facilities and customers are located primarily in the United States.

In analyzing our operating performance, we focus on the following factors that affect our business and are important to consider when reviewing our financial and operating results:

•  containerboard and corrugated products demand;

•  corrugated products and containerboard pricing and mix;

•  cost trends and volatility for our major costs, including wood and recycled fiber, purchased fuels, electricity, labor and fringe benefits, and transportation costs; and

•  cash flow from operations and capital expenditures.

The cost to manufacture containerboard is dependent, in large part, on the costs of wood fiber, recycled fiber, purchased fuels, electricity and labor and fringe benefits. Excluding the cost of containerboard, labor and benefits costs make up the largest component of corrugated products’ manufactured costs.

The market for containerboard is generally subject to changes in the U.S. economy. Historically, supply and demand, as well as industry-wide inventory levels, have influenced prices of containerboard and corrugated products. In addition to U.S. shipments, approximately 10% of domestically produced containerboard has been exported annually for use in other countries.

Industry Conditions

Market conditions for containerboard and corrugated products remained favorable during the first quarter of 2011. As reported by the Fibre Box Association, industry-wide shipments of corrugated products increased 2.0% for the three months ended March 31, 2011 compared to the same period in 2010 and March corrugated products shipments were up 4.1% above March 2010 levels. Containerboard industry production increased 1.8% in the first quarter 2011 compared to the first quarter of 2010 and reported industry containerboard inventories at the end of the first quarter 2011 were at the second lowest level for March in 30 years at approximately 2.3 million tons. Published prices for containerboard did not change during first quarter 2011.

PCA Operations Summary

During the first quarter of 2011, we produced approximately 602,000 tons of containerboard at our mills and sold about 7.9 billion square feet (“bsf”) of corrugated products. Our corrugated products shipments were up 3.1% compared to the first quarter of 2010. Containerboard volume sold to domestic and export customers increased 1.0% for the three months ended March 31, 2011 compared to the same period in 2010. Sales prices of containerboard and corrugated products were higher than the first quarter of 2010 as a result of January and April 2010 containerboard price increases and the pass-through of those price increases to corrugated products.

Industry published recycled fiber prices were up compared to the first quarter 2010 average price by almost 20% and increased approximately $5 per ton, or 3%, compared to the fourth quarter 2010. Purchased fuel costs in the first quarter of 2011 increased 7% compared to the fourth quarter 2010, and over the same time period electricity prices increased 4%. Transportation costs increased compared to both first quarter 2010 and fourth quarter 2010 driven by higher diesel prices. Energy costs in the second quarter of 2011 are expected to increase driven by increased electricity and fuel prices partially offset by lower usage associated with warmer weather. Chemical costs increased about 35% over first quarter 2010 and were up 5% over fourth quarter 2010 levels. Wood fiber costs increased compared to the fourth quarter of 2010 but were lower than last year’s first quarter.

18

As disclosed in Note 15 to the condensed consolidated financial statements, the Company is a producer of black liquor, which is considered an alternative fuel when mixed with diesel, making the black liquor an alternative fuel eligible for a $0.50 per gallon refundable alternative fuel mixture tax credit through December 31, 2009. During the first quarter of 2010, the IRS released a memorandum which provided clarification about the calculation of the alternative fuel mixture credit for black liquor. As a result, during the first quarter of 2010 the Company released the reserve of $9.2 million that was established in 2009 due to the ambiguity in the calculation of the credit. This reserve release resulted in additional income of $9.2 million, which was recorded in alternative fuel mixture tax credits on the income statement in the first quarter of 2010.

Excluding the impact of the tax credit described above and asset disposal charges related to our mill energy projects and facility closure costs, we earned net income of $39.5 million ($0.39 per diluted share) in the first quarter of 2011 compared with $12.5 million ($0.12 per diluted share) in the first quarter of 2010. Management uses these measures to focus on PCA’s on-going operations and assess its operating performance and believes that it is useful to investors because it enables them to perform meaningful comparisons of past and present operating results. Reconciliations to the most comparable measure reported in accordance with GAAP are included elsewhere in this section under “Reconciliations of Non-GAAP Financial Measures to Reported Amounts.”

Looking ahead to the second quarter of 2011, our earnings, excluding special items, are expected to be lower than the first quarter of 2011 due to increased planned mill downtime and inflationary cost pressures. Annual maintenance outages and capital project related downtime will require planned downtime at each of our four mills. Total planned downtime and slowbacks will reduce mill production by about 39,000 tons, or about 17,000 tons more than the first quarter, and will increase production costs and annual outage related maintenance costs. We also expect inflationary cost pressures to continue as transportation, energy and chemical costs are currently higher than first quarter averages. Our corrugated products shipments are expected to increase and energy usage is expected to decrease with warmer weather.

Results of Operations

Three Months Ended March 31, 2011 Compared to Three Months Ended March 31, 2010

The historical results of operations of PCA for the three months ended March 31, 2011 and 2010 are set forth below:

	Three Months Ended
	March 31,
	2011			2010			Change
(In thousands)
Net sales	$	629,500		$	550,732		$	78,768
Income from operations	$	65,903		$	33,616		$	32,287
Interest expense, net		(6,903	)		(8,723	)		1,820
Income before taxes		59,000			24,893			34,107
Provision for income taxes		(21,583	)		(5,699	)		(15,884	)
Net income	$	37,417		$	19,194		$	18,223

Net Sales

Net sales increased by $78.8 million, or 14.3%, for the three months ended March 31, 2011 from the comparable period in 2010, primarily as a result of increased sales prices ($58.0 million) and higher sales volumes ($20.8 million) of corrugated products and containerboard to third parties.

Corrugated products shipments for the first quarter increased 3.1% compared to the first quarter of 2010 and on ashipments-per-workday basis increased 1.5%. Total corrugated products volume sold for the three months ended March 31, 2011 increased 0.3 billion square feet (“bsf”) to 7.9 bsf compared to 7.6 bsf in the first quarter of 2010. The percentage increase, on a shipments per workday basis, was lower due to one more workday in the first quarter of 2011 (64 days), those days not falling on a weekend or holiday, than the first quarter of 2010 (63 days).

19

Containerboard volume sold to outside domestic and export customers increased 1.0% for the three months ended March 31, 2011 compared to the same period in 2010. Containerboard mill production during the first quarter was 602,000 tons compared to 569,000 tons during the first quarter of 2010.

Income from Operations

Income from operations increased by $32.3 million, or 96.1%, for the three months ended March 31, 2011 compared to the three months ended March 31, 2010. Excluding special items, income from operations increased $40.8 million, primarily due to higher sales prices ($58.0 million) and volume ($9.7 million). Partially offsetting these items were increased costs for chemicals ($4.9 million), transportation ($4.8 million), labor ($3.8 million), medical and worker’s compensation ($3.1 million), incentive compensation ($3.0 million), recycled fiber ($1.7 million), other fringe benefits ($1.6 million) and the impact of severe winter weather ($3.5 million).

Gross profit increased $46.3 million, or 53.4%, for the three months ended March 31, 2011 from the comparable period in 2010, primarily due to the sales price and volume increases described above. Gross profit as a percentage of net sales increased to 21.2% of net sales for first quarter 2011 compared to 15.8% in the first quarter of 2010.

Selling and administrative expenses increased $3.7 million, or 8.3%, for the three months ended March 31, 2011 compared to the same period in 2010, as a result of higher salaries and fringe benefits ($2.6 million) from annual merit increases, as well as the timing of incentive compensation charges. Other increases included travel, entertainment and meeting costs ($0.6 million) and broker commissions ($0.3 million).

Corporate overhead increased $2.9 million, or 23.1%, for the three months ended March 31, 2011 compared to the same period in 2010, primarily due to higher salaries and fringe benefits ($2.4 million) from annual merit increases as well as the timing of incentive compensation charges and increased expenses related to outside services for legal matters ($0.6 million).

Other expense for the three months ended March 31, 2011 decreased $1.8 million or 32.3% compared to the first quarter of 2010, primarily due to expense related to the closure of the Ackerman, Mississippi sawmill in the first quarter of 2010 ($2.0 million).

Interest Expense, Net and Income Taxes

Net interest expense decreased $1.8 million, or 20.9%, for the three months ended March 31, 2011 from the three months ended March 31, 2010, primarily as a result of higher capitalized interest ($1.3 million) being recorded related to the Counce and Valdosta major energy optimization projects during the three months ended March 31, 2011 compared to the same period in 2010.

PCA’s effective tax rate was 36.6% for the three months ended March 31, 2011 and 22.9% for the comparable period in 2010 due to the impact of recording the alternative fuel mixture tax credits in 2010. Excluding the impact of the tax credits, the 2010 effective tax rate would have been 36.4% for the three months ended March 31, 2010. The effective tax rate varies from the U.S. federal statutory tax rate of 35% principally due to the impact of the alternative fuel mixture tax credit (in 2010), state and local income taxes, and the domestic manufacturers’ deduction. PCA had no material changes to its uncertain tax positions under ASC 740, “Income Taxes,” during the first quarter of 2011. In March 2011, the Company was notified by the Internal Revenue Service that it will begin its review of the 2008 and 2009 federal tax returns in the second quarter of 2011.

Net cash provided by operating activities for the three months ended March 31, 2011 was $64.0 million compared to $14.5 million for the three months ended March 31, 2010, an increase of $49.4 million, or 340.9%. Net income, excluding the income from the tax credits (described in Note 15 to the financial statements included in this report) of $9.2 million in 2010, was $37.4 million and $10.0 million, respectively, for the first three months of 2011 and 2010, an increase of $27.4 million that increased net cash provided by operating activities. Additionally, requirements for operating assets and liabilities were lower by $21.2 million in 2011 compared to 2010. Cash requirements for operating activities are subject to PCA’s operating needs, the timing of collection of receivables and payments of payables and expenses, and seasonal fluctuations in the our operations.

Investing Activities

Net cash used for investing activities for the three months ended March 31, 2011 increased $2.2 million, or 3.5%, to $66.5 million, compared to the three months ended March 31, 2010. The increase was primarily related to higher additions to property, plant and equipment of $1.6 million during the three months ended March 31, 2011 compared to the same period in 2010.

Financing Activities

Net cash used for financing activities totaled $21.0 million for the three months ended March 31, 2011, a difference of $7.6 million, or 57.1%, compared to the same period in 2010. The difference was primarily attributable to repurchases of PCA common stock of $19.1 million during the first three months of 2011, partially offset by $9.9 million in proceeds from the settlement of treasury locks in February 2011. On February 22, 2011, PCA announced that its board of directors authorized an increase in the quarterly dividend from $0.15 to $0.20 per share of its common stock, beginning with the dividend paid on April 15, 2011. The timing and amount of future dividends are subject to the determination of PCA’s board of directors.

PCA’s primary sources of liquidity are net cash provided by operating activities, borrowings under PCA’s revolving credit facility, and additional borrowings under PCA’s receivables credit facility. As of March 31, 2011, PCA had $172.2 million in unused borrowing capacity under its existing credit agreements, net of the impact on this borrowing capacity of $18.8 million of outstanding letters of credit. Currently, PCA’s primary uses of cash are for operations, capital expenditures, debt service and declared common stock dividends, which it expects to be able to fund from these sources.

The following table provides the outstanding balances and the weighted average interest rates as of March 31, 2011 for PCA’s revolving credit facility, the receivables credit facility, and the senior notes:

						Projected
	Balance at		Weighted			Annual
	March 31,		Average			Cash Interest
Borrowing Arrangement	2011		Interest Rate			Payments
(In thousands)
Revolving Credit Facility	$	—		N/A			N/A
Receivables Credit Facility		109,000		1.09	%	$	1,188
53/4% Senior Notes (due August 1, 2013)		400,000		5.75			23,000
61/2% Senior Notes (due March 15, 2018)		150,000		6.50			9,750
Total	$	659,000		5.15	%	$	33,938

The above table excludes unamortized debt discount of $0.8 million at March 31, 2011. It also excludes from the projected annual cash interest payments, the non-cash income from the annual amortization of the $22.8 million received in July 2003 and the non-cash expense from the annual amortization of the $4.4 million paid in March 2008 to settle the treasury locks related to the 53/4% senior notes due 2013 and 61/2% senior notes due 2018. The amortization is being recognized over the terms of the 53/4% senior notes due 2013 and 61/2% senior notes due 2018 and is included in interest expense, net.

On March 1, 2011, PCA renewed the receivables credit facility, which was scheduled to expire on March 1, 2011, to February 28, 2012.

The instruments governing PCA’s indebtedness contain financial and other covenants that limit, among other things, the ability of PCA and its subsidiaries to:

•  enter into sale and leaseback transactions,

•  incur liens,

•  incur indebtedness at the subsidiary level,

•  enter into certain transactions with affiliates, or

•  merge or consolidate with any other person or sell or otherwise dispose of all or substantially all of the assets of PCA.

These limitations could limit corporate and operating activities.

In addition, PCA must maintain minimum net worth and maximum debt to total capitalization and minimum interest coverage ratios under the revolving credit facility. A failure to comply with the restrictions contained in the revolving credit facility could lead to an event of default, which could result in an acceleration of any outstanding indebtednessand/or prohibit PCA from drawing on the revolving credit facility. Such an acceleration may also constitute an event of default under the senior notes indentures and the receivables credit facility. As of March 31, 2011, PCA was in compliance with these covenants.

PCA currently expects to incur capital expenditures of $255.0 million in 2011, including $115.0 million for major energy optimization projects at its Counce and Valdosta mills and $40.0 million for strategic projects in the box plants. The remaining $100.0 million in expenditures will be used primarily for maintenance capital, cost reduction, business growth and environmental compliance. As of March 31, 2011, PCA spent $64.7 million for capital expenditures and had committed to spend an additional $116.0 million in the remainder of 2011 and beyond.

PCA believes that net cash generated from operating activities, available cash reserves, available borrowings under its committed credit facilities and available capital through access to capital markets will be adequate to meet its liquidity and capital requirements, including payments of any declared common stock dividends, for the foreseeable future. As its debt or credit facilities become due, PCA will need to repay, extend or replace such facilities, which will be subject to future economic conditions and financial, business and other factors, many of which are beyond PCA’s control.

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. PCA periodically enters into derivatives in order to minimize these risks, but not for trading purposes. For a discussion of derivatives and hedging activities, see Note 10 to PCA’s unaudited condensed consolidated financial statements included elsewhere in this report.

The interest rates on approximately 84% 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 $1.1 million annually. In the event of a change in interest rates, management could take actions to mitigate its exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, the sensitivity analysis assumes no changes in PCA’s financial structure.

Environmental Matters

PCA is subject to, and must comply with, a variety of federal, state and local environmental laws, particularly those relating to air and water quality, waste disposal and the cleanup of contaminated soil and groundwater. The most significant of these laws affecting the Company are:

•  Resource Conservation and Recovery Act (RCRA);

•  Clean Water Act (CWA);

•  Clean Air Act (CAA);

•  The Emergency Planning and CommunityRight-to-Know-Act (EPCRA);

•  Toxic Substance Control Act (TSCA); and

•  Safe Drinking Water Act (SDWA).

PCA believes that it is currently in material compliance with these and all applicable environmental rules and regulations. Because environmental regulations are constantly evolving, the Company has incurred, and will continue to incur, costs to maintain compliance with these and other environmental laws. PCA works diligently to anticipate and budget for the impact of applicable environmental regulations, and does not currently expect that future environmental compliance obligations will materially affect its business or financial condition.

23

In 2004, the U.S. Environmental Protection Agency (the “EPA”) published the Boiler MACT regulations affecting certain industrial boilers. These regulations were vacated and remanded by the U.S. Court of Appeals for the D.C. Circuit in 2007. The EPA proposed final regulations in 2011, which would require compliance in 2014. PCA is currently assessing the impact of these regulations on its operations which could require significant modifications to certain of PCA’s boilers. Due to the complexity of these regulations, and the potential for future regulatory or judicial modification to these regulations, the timing and amount of expenditures to be made by PCA are uncertain, but could be significant during the period before compliance is required.

Impact of Inflation

PCA does not believe that inflation has had a material impact on its financial position or results of operations during the three-month periods ending March 31, 2011 and 2010.

Off-Balance Sheet Arrangements

PCA does not have any off-balance sheet arrangements as of March 31, 2011 that would require disclosure under SEC FR-67, “Disclosure in Management’s Discussion and Analysis About Off-Balance Sheet Arrangement and Aggregate Contractual Obligations.”

Critical Accounting Policies and Estimates

Management’s discussion and analysis of PCA’s 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 the Company 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 bad debts, inventories, intangible assets, pensions and other postretirement benefits, income taxes, contingencies and litigation. 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 Annual Report onForm 10-K for the year ended December 31, 2010, a discussion of its critical accounting policies which it believes affect its more significant judgments and estimates used in the preparation of its consolidated financial statements. PCA has not made any changes in any of these critical accounting policies during the first three months of 2011.

Forward-Looking Statements

Some of the statements in this Quarterly Report onForm 10-Q, and in particular, statements found in 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;

•  containerboard and corrugated products general industry conditions, including competition, product demand and product pricing;

•  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

24

•  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. In view of 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 onForm 10-K for the year ended December 31, 2010.

Item 3.   Quantitative and Qualitative Disclosures About Market Risk.

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 onForm 10-Q.

Item 4.   Controls and Procedures.

PCA maintains disclosure controls and procedures (as defined inRule 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 March 31, 2011. 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 March 31, 2011.

During the quarter ended March 31, 2011, 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.

PART II

OTHER INFORMATION

Item 1.   Legal Proceedings.

During September and October 2010, PCA and eight other U.S. and Canadian containerboard producers were named as defendants in five purported class action lawsuits filed in the United States District Court for the Northern District of Illinois, alleging violations of the Sherman Act. The lawsuits have been consolidated in a single complaint under the captionKleen Products LLC v Packaging Corp. of America et al.The consolidated complaint alleges that the defendants conspired to limit the supply of containerboard, and that the purpose and effect of the alleged conspiracy was to artificially increase prices of containerboard products during the period of August 2005 to the time of filing of the complaints. The complaint was filed as a purported class action suit on behalf of all purchasers of containerboard products during such period. The complaint seeks treble damages and costs, including attorney’s fees. The defendants’ motions to dismiss the complaint were denied by the court in April 2011. PCA believes the allegations are without merit and will defend this lawsuit vigorously. However, as the lawsuit is in preliminary stages, PCA is unable to predict the ultimate outcome or estimate a range of reasonably possible losses.

PCA is a party to various other legal actions arising in the ordinary course of our business. These legal actions cover a broad variety of claims spanning our entire business. As of the date of this filing, we believe it is not reasonably possible that the resolution of these legal actions will, individually or in the aggregate, have a material adverse effect on our financial condition, results of operations or cash flows.
