NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1. BASIS OF PRESENTATION

The Consolidated Statement of Income for the three-month period ended March 31,
2006, and 2005, the Condensed Consolidated Statement of Financial Position at
March 31, 2006, and the Condensed Consolidated Statement of Cash Flows for the
three-month period ended March 31, 2006, and 2005, are unaudited. In our
opinion, the accompanying financial statements contain all normal recurring
adjustments necessary to present fairly the results of operations, financial
position, and cash flows for the periods indicated. These statements have been
prepared pursuant to the rules and regulations of the Securities and Exchange
Commission (SEC). They do not include all of the information and footnotes
required by generally accepted accounting principles. Accordingly, these
statements should be read in conjunction with Pactiv's Form 10-K for the year
ended December 31, 2005, which may be found at www.pactiv.com, under the
Investor Relations link in the subsection entitled "SEC Filings", or a free copy
may be obtained by contacting Investor Relations at (866) 456-5439. Certain
reclassifications have been made to the prior-year financial information to
conform with current-year presentation.

On October 12, 2005, we completed the sale of most of our protective- and
flexible-packaging businesses to Pregis Corporation for $523 million, and
recorded an estimated loss on the sale of $50 million, net of tax. These
businesses historically were included in our Protective and Flexible Packaging
segment. In conjunction with the sale of these entities, we reviewed our
reporting segments in concert with requirements of the Statement of Financial
Accounting Standards (SFAS) No. 131, "Disclosures About Segments of an
Enterprise and Related Information." As a result, we elected to include the
retained portions of the protective-and flexible-packaging businesses in our
Foodservice/Food Packaging segment.

We have three reporting segments:

     - Consumer Products manufactures and sells disposable plastic, foam,
       molded-fiber, pressed-paperboard, and aluminum packaging products to
       consumer markets, such as grocery stores, mass merchandisers, and
       discount chains. Products include waste bags, food-storage bags, and
       disposable tableware and cookware. We sell many of our consumer products
       under well-known trademarks, such as Hefty(R).

     - Foodservice/Food Packaging manufactures and sells foam, clear plastic,
       aluminum, pressed-paperboard, and molded-fiber packaging to customers in
       the food distribution channel who prepare and process food for
       consumption. Customers include foodservice distributors, restaurants and
       other institutional foodservice outlets, food processors, and grocery
       chains.

     - Other relates to corporate and administrative-service operations and
       retiree-benefit income and expense.

The accounting policies of the reporting segments are the same as those for
Pactiv as a whole. Where discrete financial information is not available by
segment, reasonable allocations of expenses and assets/liabilities are used.

NOTE 2. SUMMARY OF ACCOUNTING POLICIES

For a complete discussion of our accounting policies, refer to Pactiv's most
recent filing on Form 10-K.

STOCK-BASED COMPENSATION

Effective January 1, 2006, we adopted the fair value method of accounting for
employee stock-compensation costs required by SFAS No. 123(R), "Share-Based
Payments." Prior to that date, we used the intrinsic value method in accordance
with requirements of Accounting Principles Board (APB) Opinion No. 25,
"Accounting for Stock Issued to Employees." The following table shows the
effects on net income and earnings per share had the fair value method been used
in determining stock-based compensation costs in the first quarter of 2005.

</Table>

On November 28, 2005, our board of directors decided to replace stock options
with performance shares under our long-term compensation program. As part of
this change, the board accelerated the vesting of all unvested stock options as
of that date. Accelerating the vesting of options will give rise to a reduction
in compensation costs going forward, compared with what would be the case if we
had commenced the expensing of these options in 2006.

ACCOUNTS AND NOTES RECEIVABLE

On a recurring basis, we sell an undivided interest in a pool of trade
receivables meeting certain criteria to a third party as an alternative to debt
financing. Such sales, which represent a form of off-balance-sheet financing,
are recorded as a reduction of accounts and notes receivable in the Statement of
Financial Position. The related proceeds are included in cash provided by
operating activities in the Statement of Cash Flows. No receivables were sold at
March 31, 2006, while amounts totaling $85 million were sold at March 31, 2005.
Discounts and fees related to these sales were immaterial in the first quarter
of 2006 and 2005. These expenses are included in other expense in the Statement
of Income. In the event that either Pactiv or the third-party purchaser of the
trade receivables were to discontinue this program, our debt would increase, or
our cash balance would decrease, by an amount corresponding to the level of sold
receivables at such time.

CHANGES IN ACCOUNTING PRINCIPLES

In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS
No. 123(R), which requires that the fair value of all share-based payments to
employees, including stock options, be recognized in financial statements. SFAS
No. 123(R) superceded APB Opinion No. 25, which required that the intrinsic
value method be used in determining compensation expense for share-based
payments to employees. Under SFAS No. 123(R), employee-compensation expense is
based on the grant-date fair value of awards, and is recognized in the Statement
of Income over the period that recipients of awards are required to provide
related service (normally the vesting period).

                                        7
<PAGE>

We adopted SFAS No. 123(R) using the modified prospective method as of January
1, 2006. The impact if SFAS No. 123(R) had been adopted in prior periods is
shown under the "Stock Based Compensation" section of this note. The cumulative
effect of adopting SFAS No. 123(R) in the first quarter of 2006 was immaterial.

We elected to use the simplified method in calculating our additional paid-in
capital pool upon adoption of SFAS No. 123(R) as described in FASB Staff
Position No. FAS 123(R) -- 3, "Transition Election Related to Accounting for the
Tax Effects of Share-Based Payment Awards" (the "simplified method").

SFAS No. 123(R) also requires that tax deductions in excess of recognized
compensation costs be reported as cash flow from financing activities, rather
than as cash flow from operating activities. There was no reduction in taxes
paid in the first quarter of 2006 or 2005 from such "excess" tax-deduction
benefits.

NOTE 3. RESTRUCTURING AND OTHER

In the first quarter of 2004, we announced a restructuring program to reduce
manufacturing capacity and overhead costs and to reinvest a portion of the
related savings in strategic growth initiatives. The total cost of the
restructuring program was $84 million; $54 million after tax, or $0.35 per
share, covering severance, asset write-offs, and other, which consisted
principally of asset-removal costs. The majority of the program was executed in
the second quarter of 2004.

In the first quarter of 2005, we recorded restructuring and other charges of $6
million, $4 million after tax, or $0.02 per share, related to this program. In
the first quarter of 2006, we recorded a restructuring and other credit of $1
million. No further charges related to this program are anticipated.

After-tax cash payments related to the restructuring and other actions were
immaterial in the first quarter of 2006 and $4 million for the first quarter of
2005.

The following summarizes the impacts of restructuring and related actions.

NOTE 4. DISCONTINUED OPERATIONS

For the quarter ended March 31, 2005, sales from discontinued operations (see
Note 1) were $219 million and income from discontinued operations before taxes
was $1 million. No income from discontinued operations was recorded in the first
quarter of 2006.

At March 31, 2006, and December 31, 2005, liabilities related to discontinued
operations totaled $20 million and included obligations related to income taxes,
certain royalty payments, and the costs of closing a facility in Europe.

NOTE 5. ACQUISITIONS

On March 15, 2005, we acquired Newspring Industrial Corp. (Newspring) for $98
million. Newspring is a leading manufacturer of thin wall, injection-molded
polypropylene products for use in the take-out, delicatessen, and foodservice
markets. We paid $87 million for the stock of Newspring and recorded liabilities
of

                                        8
<PAGE>

$11 million for anticipated future payments related to non-compete agreements
and other items. Appraisals of the fair-market value of the assets acquired were
finalized in the first quarter of 2006. This resulted in goodwill being reduced
by $9 million and other intangibles and property, plant, and equipment being
increased by $2 million and $7 million, respectively.

NOTE 6. GOODWILL AND INTANGIBLE ASSETS

In the first quarter of 2006, we acquired 2,001,900 shares of our common stock
at an average price of $23.08 per share, or a total outlay of $46 million. In
the first quarter of 2005, we did not repurchase any of our common stock.

GRANTOR TRUST

In November 1999, we established a grantor trust and reserved 3,200,000 shares
of Pactiv common stock for the trust. These shares were issued to the trust in
January 2000. This so-called "rabbi trust" is designed to assure the payment of
deferred-compensation and supplemental pension benefits. These shares are not
considered outstanding for purposes of financial reporting.

the right to change post-retirement plans.

NOTE 12. CONTINGENCIES

LITIGATION

In November 2004, a law firm purporting to represent more than 1,400 potential
plaintiffs, who allegedly experienced various personal injuries and property
damages as a result of the alleged release of chemical substances from a
wood-treatment facility in Lockhart, Alabama, during the period from 1963 to
1998, notified us that it believes we are at least partially responsible for
some of such alleged injuries and damages. A predecessor of Pactiv owned the
facility from 1978 to 1983. The letter was addressed to Pactiv and
Louisiana-Pacific Corporation, the current owner of the facility, to whom a
predecessor of Pactiv sold the

                                        11
<PAGE>

facility in 1983. As of the date of this report, 10 lawsuits have been filed in
state and federal court in Alabama, seeking unspecified damages. We are not
currently able to quantify our financial exposure, if any, relating to this
matter. We intend to defend these lawsuits vigorously and any other lawsuits
that may be commenced against us by the potential plaintiffs.

In March 2005, we filed a declaratory-judgment action in the United States
District Court, Eastern District of Michigan, related to a superfund site in
Filer City, Michigan. The final clean-up remedy for the site was pursuant to a
U.S. Environmental Protection Agency (EPA) Record of Decision and Administrative
Order in 1993, in which the EPA expressly determined that conditions at the site
posed no current or potentially unacceptable risk to human health or the
environment. We contend that, because of the federal EPA action in 1993, the
Michigan Department of Environmental Quality is precluded from demanding that
Pactiv undertake additional investigative and remedial work at the site. While
we cannot predict the outcome of this proceeding, based on our assessment of the
facts and circumstances now known, we do not believe it will have a material
effect on our financial position.

We are party to other legal proceedings arising from our operations. We
establish reserves for claims and proceedings when it is probable that
liabilities exist and where reasonable estimates of such liabilities can be
made. While it is not possible to predict the outcome of any of these matters,
based on our assessment of the facts and circumstances now known, we do not
believe that any of these matters, individually or in the aggregate, will have a
material adverse effect on our financial position. However, actual outcomes may
be different from those expected and could have a material effect on our results
of operations or cash flows in a particular period.

ENVIRONMENTAL MATTERS

We are subject to a variety of environmental and pollution-control laws and
regulations. From time to time, we identify costs or liabilities arising from
compliance with environmental laws and regulations. When related liabilities are
probable and can be reasonably estimated, we establish appropriate reserves.
Estimated liabilities may change as additional information becomes available. We
appropriately adjust our reserves as new information on possible clean-up costs,
expense and effectiveness of alternative clean-up methods, and other potential
liabilities is received. We do not expect that any additional liabilities
recorded as a result of the availability of new information will have a material
adverse effect on our financial position. However, such costs could have a
material effect on our results of operations or cash flows in a particular
period.

The preceding notes are an integral part of the foregoing financial statements.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

BASIS OF PRESENTATION

Financial statements for all periods presented in this report have been prepared
on a consolidated basis in accordance with generally accepted accounting
principles consistently applied. All per-share information is presented on a
diluted basis unless otherwise noted. Certain reclassifications have been made
to the prior-year financial information to conform with current-year
presentation.

On October 12, 2005, we completed the sale of most of our protective- and
flexible-packaging businesses to Pregis Corporation for $523 million, and
recorded an estimated loss on the sale of $50 million, net of tax. These
businesses historically were included in our Protective and Flexible Packaging
segment. In conjunction with the sale of these entities, we reviewed our
reporting segments in concert with requirements of the Statement of Financial
Accounting Standards (SFAS) No. 131, "Disclosures About Segments of an
Enterprise and Related Information." As a result, we elected to include the
retained portions of the protective-and flexible-packaging businesses in our
Foodservice/Food Packaging segment.

We have three reporting segments:

     - Consumer Products manufactures and sells disposable plastic, foam,
       molded-fiber, pressed-paperboard, and aluminum packaging products to
       consumer markets, such as grocery stores, mass merchandisers,

                                        12
<PAGE>

       and discount chains. Products include waste bags, food-storage bags, and
       disposable tableware and cookware. We sell many of our consumer products
       under well-known trademarks, such as Hefty(R).

     - Foodservice/Food Packaging manufactures and sells foam, clear plastic,
       aluminum, pressed-paperboard, and molded-fiber packaging to customers in
       the food distribution channel who prepare and process food for
       consumption. Customers include foodservice distributors, restaurants and
       other institutional foodservice outlets, food processors, and grocery
       chains.

     - Other relates to corporate and administrative-service operations and
       retiree-benefit income and expense.

The accounting policies of the reporting segments are the same as those for
Pactiv as a whole. Where discrete financial information is not available by
segment, reasonable allocations of expenses and assets/liabilities are used.

RESTRUCTURING AND OTHER

In the first quarter of 2004, we announced a restructuring program to reduce
manufacturing capacity and overhead costs, and to reinvest a portion of the
related savings in strategic growth initiatives. The majority of the program was
executed in the second quarter of 2004. In the first quarter of 2005, the
company recorded restructuring and other charges of $6 million, $4 million after
tax, or $0.02 per share, related to this program. In the first quarter of 2006,
we recorded a restructuring and other credit of $1 million. No further charges
related to this program are anticipated.

After-tax cash payments related to the restructuring and other actions were
immaterial in the first quarter of 2006 and $4 million for the first quarter of
2005.

The following summarizes the impacts of restructuring and related actions.

THREE MONTHS ENDED MARCH 31, 2006, COMPARED WITH THREE MONTHS ENDED MARCH 31,
2005

RESULTS OF CONTINUING OPERATIONS

Significant Trends

The principal raw materials used to manufacture our products are plastic resins,
principally polystyrene and polyethylene. Average industry prices for
polystyrene were approximately 7% lower in the first quarter of 2006 than in the
same period of 2005, driven principally by softer market demand and lower
benzene prices. Lower resin costs helped improve the spread (the difference
between selling prices and raw-material costs) on our polystyrene-based products
in the first quarter of 2006. Average industry prices for polyethylene rose
approximately 19% in the first quarter of 2006, compared with the same period in
2005, fueled by higher natural-gas prices. We were able to raise selling prices
in many areas of our business to mitigate the effect of resin cost increases
over the last three years.

                                        13
<PAGE>

In late 2005, an industry-wide disruption of supply of plastic resin occurred
due to the Gulf Coast hurricanes. As a result, resin costs increased in the
fourth quarter of 2005 but decreased slightly in the first quarter of 2006.
Nevertheless, raw-material costs remain high and are still volatile. Resin costs
will likely continue to be a source of uncertainty for us in the near-term, as
oil prices remain near their historic highs. We continue to closely monitor the
resin marketplace in order to respond quickly to any raw-material cost
increases.

Our business is sensitive to other energy-related cost movements, particularly
those that affect transportation, logistics, and utility costs. Historically, we
have been able to mitigate the effect of higher energy-related costs with
productivity improvements and other cost reductions. However, if energy-related
costs increase significantly in the future, we may not be able to fully offset
such increases with productivity gains.

New consumer product lines launched in 2005 included Hefty(R) Serve 'n Store(R)
tableware, Hefty(R) Easy Grip(TM) cups, and Hefty(R) EZ Ovenware(TM) Casserole
Pans. As expected, in the first quarter of 2006, we benefited from better
operating efficiencies and the absence of one-time introduction costs related to
new-product launches in our Consumer segment. For full year 2006, the negative
impact on income from the launch of new products is expected to be about
one-half of what it was in 2005.

Sales increased 11% due to favorable pricing of 8% and higher volume from
acquisitions of 3%.

Increased Consumer Products sales reflected price increases of 11% and volume
growth of 2%. Strength in the base business, particularly in food bags and
tableware products, contributed to the volume growth. Hefty(R) Serve 'n
Store(TM) plates and bowls, as well as Hefty(R) Easy Grip(TM) party cups,
launched last year, contributed to the growth in tableware products.

Sales growth in the Foodservice/Food Packaging business was driven by price
increases of 6% and volume gains of 4%. The acquisition of Newspring in March
2005 drove the volume growth, while base-business volume was even with last
year.

the absence of one-time introduction costs related to new product launches,
offset, in part, by higher selling, general, and administrative (SG&A) costs.

We believe that focusing on operating income excluding the effect of
restructuring and other charges is a meaningful alternative way of evaluating
our operating results. Restructuring and other charges relate to actions that
will have an ongoing effect on our company. Considering such charges as being
applicable to only the periods in which they are recognized could make our
operating performance in those periods more difficult to evaluate when compared
with other periods in which there were no such charges. We use operating income
excluding restructuring and other charges to evaluate operating performance and,
along with other factors, in determining management compensation.

The following table summarizes operating income excluding restructuring and
other charges for the first quarter of 2006 and 2005.

</Table>

Total operating income excluding restructuring and other charges improved versus
2005, driven by favorable spread and the absence of one-time introduction costs
related to new product launches, offset, in part, by higher SG&A costs.

Operating income excluding restructuring and other charges for the Consumer
Products business doubled compared with 2005. The increase was due primarily to
favorable spread, as well as better operating efficiencies and the absence of
one-time introduction costs related to new product launches.

Operating income excluding restructuring and other charges for the
Foodservice/Food Packaging business increased significantly from 2005. The
increase primarily reflected spread recovery, favorable mix, and higher volume.
We continue to improve the profitability of the business by focusing on selling
higher margin products and minimizing sales of low margin products.

Operating income excluding restructuring and other charges for the Other segment
decreased from 2005, principally because of higher compensation-related expenses
and lower noncash pension income.

Net Income

We recorded net income of $51 million, or $0.35 per share, in the first quarter
of 2006, compared with $22 million, or $0.15 per share, last year. Results for
the first quarter of 2006 included the impact of restructuring and other credits
totaling $1 million, while the first quarter of 2005 included the impact of
restructuring and other charges totaling $4 million.

  Financing activities......................................   (37)   (154)      117
</Table>

The decrease in cash provided by operating activities was driven primarily by
reduced usage of our accounts receivable securitization program (See Note 2),
and accounts payable timing, offset partially by the increase in net income.

                                        16
<PAGE>

Cash used by investing activities was $13 million in the first quarter of 2006,
primarily representing capital expenditures, compared with $137 million in 2005
($98 million for the Newspring acquisition and $38 million for capital
expenditures).

Cash used by financing activities was $37 million in the first quarter of 2006,
primarily reflecting the repurchase of company stock ($46 million) and payments
related to the non-compete agreements and other items related to the Newspring
acquisition ($3 million), offset partially by the issuance of company stock ($12
million). Cash used by financing activities was $154 million in 2005, primarily
reflecting the repayment of debt related to our synthetic-lease facility ($169
million), offset partially by anticipated future payments related to non-compete
agreements and other items related to the Newspring acquisition ($11 million)
and by the issuance of company stock ($4 million).

Capital Commitments

Commitments for authorized capital expenditures totaled approximately $46
million at March 31, 2006. It is anticipated that the majority of these
expenditures will be funded over the remainder of the year from existing cash
and short-term investments and internally generated cash.

Contractual Obligations

There has been no material change in the company's aggregate contractual
obligations since the end of 2005.

Liquidity and Off-Balance-Sheet Financing

We use various sources of funding to manage liquidity. Sources of liquidity
include cash flow from operations and a 5-year, $600 million revolving-credit
facility, under which no amounts were outstanding at March 31, 2006. We were in
full compliance with financial and other covenants of the revolving-credit
agreement at the end of the first quarter of 2006. During March 2006, we signed
a commitment letter with our lenders to increase our revolving-credit facility
to $750 million. The agreement was finalized on April 19, 2006. We also use an
asset-securitization program as off-balance-sheet financing. No amounts were
securitized under this program at March 31, 2006, or December 31, 2005.

As a result of the Gulf Coast hurricanes in 2005, the supply of resin materials
was disrupted and our inventory levels were lower than normal at the end of
2005. During the first quarter of 2006, we replenished our inventories,
requiring a significant use of cash.

We have pension plans that cover substantially all of our employees. Funding of
the qualified U.S. plan is determined by the Employee Retirement Income Security
Act. Based on long-term projections and regulations in existence at March 31,
2006, we do not expect to be required to contribute cash to this plan through at
least 2014.

We believe that cash flow from operations, available cash reserves, and the
ability to obtain cash under our credit facilities and asset-securitization
program will be sufficient to meet current and future liquidity and capital
requirements.

CHANGES IN ACCOUNTING PRINCIPLES

In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS
No. 123(R), "Share-Based Payment," which requires that the fair value of all
share-based payments to employees, including stock options, be recognized in
financial statements. SFAS No. 123(R) superceded Accounting Principles Board
(APB) Opinion No. 25, "Accounting for Stock Issued to Employees." APB Opinion
No. 25 required that the intrinsic value method be used in determining
compensation expense for share-based payments to employees. Under SFAS No.
123(R), employee-compensation expense is based on the grant-date fair value of
awards and expense is recognized in the Statement of Income over the period
during which recipients of awards are required to provide service (normally the
vesting period).

We adopted SFAS No. 123(R) using the modified prospective method as of January
1, 2006. The impact if SFAS No. 123(R) had been adopted in the prior period is
shown under the "Stock Based Compensation" section of Note 2. The cumulative
effect of adopting SFAS No. 123(R) in the first quarter 2006 results was
immaterial.

We elected to use the simplified method in calculating our additional paid-in
capital pool upon adoption of SFAS No. 123(R) as described in FASB Staff
Position No. FAS 123(R) -- 3, "Transition Election Related to Accounting for the
Tax Effects of Share-Based Payment Awards" (the "simplified method").

SFAS No. 123(R) also requires that tax deductions in excess of recognized
compensation costs be reported as cash flow from financing activities, rather
than as cash flow from operating activities. There was no reduction in taxes
paid in the first quarter of 2006 or 2005 from such "excess" tax-deduction
benefits.

         CAUTIONARY STATEMENT FOR PURPOSES OF "SAFE HARBOR" PROVISIONS
            OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

Certain statements included in this Quarterly Report on Form 10-Q, including
statements in the "Management's Discussion and Analysis of Financial Condition
and Results of Operations" section and in the notes to the financial statements,
are "forward-looking statements." All statements other than statements of
historical fact, including statements regarding prospects and future results,
are forward-looking. These forward-looking statements generally can be
identified by the use of terms and phrases such as "will", "believe",
"anticipate", "may", "might", "could", "expect", "estimated", "projects",
"intends", "foreseeable future", and similar terms and phrases. These
forward-looking statements are not based on historical facts, but rather on our
current expectations or projections about future events. Accordingly, these
forward-looking statements are subject to known and unknown risks and
uncertainties. While we believe that the assumptions underlying these
forward-looking statements are reasonable and make the statements in good faith,
actual results almost always vary from expected results, and the differences
could be material.

See "Risk Factors" section (Item 1A) in our most recently filed Securities and
Exchange Commission (SEC) Form 10-K and Part II (Item 1A) of this report for
some of the factors that we believe could cause our actual results to differ
materially from future results expressed or implied by these forward-looking
statements. These factors include the following:

     - Changes in consumer demand and selling prices for our products, including
       new products that our competitors or we may introduce that could impact
       sales and margins.

     - Material substitutions and changes in costs of raw materials, including
       plastic resins, labor, utilities, or transportation that could impact our
       expenses and margins.

     - Changes in laws or governmental actions, including changes in regulations
       such as those relating to air emissions or plastics generally.

     - The availability or cost of capital could impact growth or acquisition
       opportunities.

     - Workforce factors such as strikes or other labor interruptions.

     - The general economic, political, and competitive conditions in countries
       in which we operate, including currency fluctuations and other risks
       associated with operating outside of the U. S.

     - Changes in (1) assumptions regarding the long-term rate of return on
       pension assets and other factors, (2) the discount rate, and (3) the
       level of amortization of actuarial gains and losses.

     - Proposed changes in U.S. and/or foreign governmental regulations relating
       to pension-plan funding.

     - Changes enacted by the SEC, the Financial Accounting Standards Board, or
       other regulatory or accounting bodies. See "Changes in Accounting
       Principles."

     - Competition from producers located in countries that have lower labor and
       other costs.

     - Our ability to integrate new businesses that we may acquire or to dispose
       of businesses or business segments that we may wish to divest.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

DERIVATIVE FINANCIAL INSTRUMENTS

We are exposed to market risks related to changes in foreign-currency exchange
rates, interest rates, and commodity prices. To manage these risks we may enter
into various hedging contracts in accordance with established policies and
procedures. We do not use hedging instruments for trading purposes and are not a
party to any transactions involving leveraged derivatives.

Foreign-Currency Exchange

We use foreign-currency forward contracts to hedge our exposure to adverse
changes in exchange rates, primarily related to the euro and the British pound.
Associated gains or losses offset gains or losses on underlying assets or
liabilities.

In March 2006, we entered into a forward contract for delivery in April 2006 of
30 million euros at an exchange rate of $1.207 per euro, or $36 million. This
transaction locked in the exchange rate for cash to be sent back to the U.S.
from a foreign subsidiary in April 2006.

In managing foreign-currency risk, we aggregate existing positions and hedge
residual exposures through third-party derivative contracts. The following table
summarizes foreign-currency forward contracts in effect at March 31, 2006, all
of which will mature in 2006.

Interest Rates

At March 31, 2006, we had public-debt securities of $875 million outstanding,
with fixed interest rates and maturity dates ranging from 1 to 21 years. Should
we decide to redeem these securities prior to their stated maturity, we would
incur costs based on the fair value of the securities at that time. In addition,
we had floating-rate debt of $3 million outstanding at March 31, 2006.

The following table provides information about Pactiv's financial instruments
that are sensitive to interest-rate risks.

Prior to our spin-off from Tenneco Inc., we entered into an interest-rate swap
to hedge our exposure to interest-rate movements. We settled this swap in
November 1999, incurring a $43 million loss, which is being recognized as
additional interest expense over the average life of the underlying debt.

ITEM 4. CONTROLS AND PROCEDURES

Our disclosure controls and procedures (as defined in Exchange Act Rules
13a-15(e) and 15d-15(e)) are designed to ensure that information required to be
disclosed by us in the reports we file or submit under the Securities Exchange
Act is recorded, processed, summarized, and reported within the appropriate time
periods. We, under the supervision and with the participation of our management,
including our principal executive officer and principal financial officer, have
evaluated the effectiveness of our disclosure controls and procedures, and we
and such officers have concluded that such controls and procedures were adequate
and effective as of March 31, 2006.

There were no changes in internal controls over financial reporting (as defined
in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the quarter ended March
31, 2006, that materially affected, or are reasonably likely to materially
affect, our internal controls over financial reporting.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In August 2004, our board of directors approved a plan to repurchase up to 5
million shares of our common stock. In August 2005 and October 2005, the board
of directors approved the repurchase of an additional 6.1 million and 6.5
million shares, respectively. As of March 31, 2006, the remaining number of
shares authorized for repurchase under these plans was 5.9 million. We
repurchase shares using open market or privately negotiated transactions.
Repurchased shares are held in treasury for general corporate purposes. There
are no expiration dates for the current share-repurchase authorizations.

The following table summarizes our stock repurchases in the first quarter of
2006.
