BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	3 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The interim condensed consolidated financial statements have been prepared in accordance with the U.S. Securities and Exchange Commission (“SEC”) instructions to Quarterly Reports on Form 10-Q and include all of the information and disclosures required by accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting. The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the interim condensed consolidated financial statements and accompanying notes. Actual amounts could differ from those estimates. The fiscal year of Greif, Inc. and its subsidiaries (the “Company”) begins on November 1 and ends on October 31 of the following year. Any references to years or to any quarter of those years, relates to the fiscal year or quarter, as the case may be, ended in that year, unless otherwise stated. The information filed herein reflects all adjustments that are, in the opinion of management, necessary for a fair presentation of the interim condensed consolidated balance sheets as of January 31, 2021 and October 31, 2020, the interim condensed consolidated statements of income and comprehensive income for the three months ended January 31, 2021 and 2020 and the interim condensed consolidated statements of cash flows for the three months ended January 31, 2021 and 2020 of the Company. The interim condensed consolidated financial statements include the accounts of Greif, Inc., all wholly-owned and consolidated subsidiaries and investments in limited liability companies, partnerships and joint ventures in which it has controlling influence or is the primary beneficiary. Non-majority owned entities include investments in limited liability companies, partnerships and joint ventures in which the Company does not have controlling influence and are accounted for using either the equity or cost method, as appropriate. The unaudited interim condensed consolidated financial statements included in the Quarterly Report on Form 10-Q (this “Form 10-Q”) should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for its fiscal year ended October 31, 2020 (the “2020 Form 10-K”). Effective the first quarter 2021, the Company adjusted its reportable segments. The presentation of prior periods throughout Part I Item 1 of this Form 10-Q has been modified to reflect the new segment reporting structure. See Note 12 to the Interim Condensed Consolidated Financial Statements for additional information. COVID-19 The preparation of financial statements requires management to make estimates and assumptions that affect the amounts of assets, liabilities, revenues and expenses reported in such financial statements. The estimates and assumptions used in the preparation of the financial statements contained in this Form 10-Q do not reflect material changes to the estimates and assumptions disclosed in the 2020 Form 10-K. Nevertheless, the Company's actual results and outcomes during the three months ended January 31, 2021 have been impacted by the COVID-19 pandemic, which has caused market disruption and volatility. Because the scope, duration and magnitude of the effects of the COVID-19 pandemic continue to evolve, the Company cannot, at this time, predict the impact the pandemic will have on its future consolidated financial position, cash flows or results of operations; however, the impact could be material. The Company's future financial results and operations depend in part on the duration and severity of the pandemic and what actions are taken to mitigate the outbreak. Newly Adopted Accounting Standards In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, “Financial Instruments – Credit Losses.” This ASU sets forth a current expected credit loss model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. The Company adopted this ASU on November 1, 2020. The adoption of this guidance did not have a material impact on financial position, results of operations, comprehensive income, cash flows or disclosures. Recently Issued Accounting Standards In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes", which is intended to simplify accounting for income taxes. This ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years, with early adoption permitted. The effective date for the Company to adopt this ASU is November 1, 2021. The Company is in the process of determining the potential impact of adopting this guidance on its financial position, results of operations, comprehensive income, cash flow and disclosures.

2019 Credit Agreement

On February 11, 2019, the Company and certain of its subsidiaries entered into an amended and restated senior secured credit agreement (the “2019 Credit Agreement”) with a syndicate of financial institutions. The Company's obligations under the 2019 Credit Agreement are guaranteed by certain of its U.S. and non-U.S. subsidiaries.

The 2019 Credit Agreement provides for (a) an $800.0 million secured revolving credit facility, consisting of a $600.0 million multicurrency facility and a $200.0 million U.S. dollar facility, maturing on February 11, 2024, (b) a $1,275.0 million secured term loan A-1 facility with quarterly principal installments commencing on April 30, 2019 and continuing through maturity on January 31, 2024, and (c) a $400.0 million secured term loan A-2 facility with quarterly principal installments commencing on April 30, 2019 and continuing through maturity on January 31, 2026. In addition, the Company has an option to add an aggregate of $700.0 million to the secured revolving credit facility under the 2019 Credit Agreement with the agreement of the lenders. The revolving credit facility is available to fund ongoing working capital and capital expenditure needs, for general corporate purposes, and to finance acquisitions.

On November 13, 2020 the Company and certain of its U.S. subsidiaries entered into an incremental term loan agreement (the "Incremental Term A-3 Loan Agreement") with a syndicate of farm credit institutions. The Incremental Term A-3 Loan Facility provides for a loan commitment in the aggregate principal amount of $225.0 million that must be funded in a single draw on a business day occurring on or before July 15, 2021 (the "Incremental Term A-3 Loan"). The Incremental Term A-3 Loan matures on July 15, 2026, with quarterly installments of principal payable on the last day of each fiscal quarter commencing with the first such date to occur after the funding date. The Incremental Term A-3 Loan has, for all material purposes, the identical terms and provisions as the term A-1 and the term A-2 loans under the 2019 Credit Agreement, discussed above. The Company's obligations with respect to the Incremental Term A-3 Loan will constitute obligations under the 2019 Credit Agreement and will be secured and guaranteed with the other obligations as provided in the under the 2019 Credit Facility on a pari passu basis. The Company intends to draw upon the Incremental Term A-3 Loan prior to July 15, 2021, and use the loan proceeds to pay all of the outstanding principal of and interest on the Senior Notes due 2021, discussed below.

As of January 31, 2021, $1,462.5 million was outstanding under the 2019 Credit Agreement. The current portion of such outstanding amount was $133.6 million, and the long-term portion was $1,328.9 million. The weighted average interest rate for borrowings under the 2019 Credit Agreement was 1.95% for the three months ended January 31, 2021. The actual interest rate for borrowings under the 2019 Credit Agreement was 1.90% as of January 31, 2021. The deferred financing costs associated with the term loan portion of the 2019 Credit Agreement totaled $8.0 million as of January 31, 2021 and are recorded as a direct deduction from the balance sheet line Long-Term Debt. The deferred financing costs associated with the revolver portion of the 2019 Credit Agreement totaled $5.6 million as of January 31, 2021 and are recorded within Other Long-Term Assets.

Senior Notes due 2027

On February 11, 2019, the Company issued $500.0 million of 6.50% Senior Notes due March 1, 2027 (the "Senior Notes due 2027"). Interest on the Senior Notes due 2027 is payable semi-annually commencing on September 1, 2019. The Company's obligations under the Senior Notes due 2027 are guaranteed by its U.S. subsidiaries that guarantee the 2019 Credit Agreement.

The deferred financing cost associated with the Senior Notes due 2027 totaled $2.2 million as of January 31, 2021 and are recorded as a direct deduction from the balance sheet line Long-Term Debt.

Senior Notes due 2021

On July 15, 2011, Greif, Inc.’s wholly-owned subsidiary, Greif Nevada Holdings, Inc., S.C.S., issued €200.0 million of 7.375% Senior Notes due July 15, 2021 (the "Senior Notes due 2021"). The Senior Notes due 2021 are guaranteed on a senior basis by Greif, Inc. Interest on the Senior Notes due 2021 is payable semi-annually. During the first quarter of 2021, the Company entered into the Incremental Term A-3 Loan Agreement, as described above, with the intent to utilize the proceeds from the Incremental Term A-3 Loan to pay down the Company's Senior Notes due 2021 at maturity.

United States Trade Accounts Receivable Credit Facility

On September 24, 2020, the Company amended and restated the existing receivable financing facility (the "U.S. Receivables Facility"), which currently matures on September 24, 2021. Greif Receivables Funding LLC, Greif Packaging LLC, for itself and as servicer, and certain other U.S. subsidiaries of the Company entered into a Fourth Amended and Restated Transfer and Administration Agreement, dated as of September 24, 2020 (the "Fourth Amended TAA"), with Bank of America, N.A., as the agent, managing agent, administrator and committed investor, and various investor groups, managing agents, and administrators, from time to time parties thereto. The Fourth Amended TAA provides a $250.0 million U.S. Receivables Facility that is secured by certain U.S. accounts receivable. The $224.1 million outstanding balance under the U.S. Receivables Facility as of January 31, 2021 is reported in "Long-term debt" on the interim condensed consolidated balance sheets because the Company intends to refinance this obligation on a long-term basis and has the intent and ability to consummate a long-term refinancing.

International Trade Accounts Receivable Credit Facility

On April 17, 2020, Cooperage Receivables Finance B.V. and Greif Coordination Center BVBA, an indirect wholly owned subsidiary of Greif, Inc., amended and restated the Nieuw Amsterdam Receivables Financing Agreement (the "European RFA") with affiliates of a major international bank. The amended and restated European RFA will mature April 17, 2021. The European RFA provides an accounts receivable financing facility of up to €100.0 million ($121.1 million as of January 31, 2021) secured by certain European accounts receivable. The $81.3 million outstanding on the European RFA as of January 31, 2021 is reported as "Long-term debt" on the interim condensed consolidated balance sheets because the Company intends to refinance these obligations on a long-term basis and has the intent and ability to consummate a long-term refinancing by exercising the renewal option in the respective agreement or entering into new financing arrangements.

The carrying amounts of cash and cash equivalents, trade accounts receivable, accounts payable, current liabilities and short-term borrowings as of January 31, 2021 and October 31, 2020 approximate their fair values because of the short-term nature of these items and are not included in this table.

Interest Rate Derivatives

The Company has various borrowing facilities which charge interest based on the one-month U.S. dollar LIBOR rate plus a spread.

In 2020, the Company entered into four forward starting interest rate swaps with a total notional amount of $200.0 million effective July 15, 2021, maturing on July 15, 2029. The Company receives variable rate interest payments based upon one-month U.S. dollar LIBOR, and in return the Company is obligated to pay interest at a weighted-average interest rate of 0.90% plus a spread. This effectively converted the borrowing rate on an amount of debt equal to the outstanding notional amount of the interest rate swap from a variable rate to a fixed rate.

In 2019, the Company entered into six interest rate swaps with a total notional amount of $1,300.0 million that amortize to $200.0 million over a five-year term, maturing on March 11, 2024. The outstanding notional amount as of January 31, 2021 is $600.0 million. The Company receives variable rate interest payments based upon one-month U.S. dollar LIBOR, and in return the Company is obligated to pay interest at a weighted-average interest rate of 2.49% plus a spread. This effectively converted the borrowing rate on an amount of debt equal to the outstanding notional amount of the interest rate swap from a variable rate to a fixed rate.

In 2017, the Company entered into an interest rate swap with a notional amount of $300.0 million, maturing on February 1, 2022. The Company receives variable rate interest payments based upon one-month U.S. dollar LIBOR, and in return the Company is obligated to pay interest at a fixed rate of 1.19% plus a spread. This effectively converted the borrowing rate on an amount of debt equal to the outstanding notional amount of the interest rate swap from a variable rate to a fixed rate.

These derivatives are designated as cash flow hedges for accounting purposes. Accordingly, the gain or loss on these derivative instruments are reported as a component of other comprehensive income and reclassified into earnings in the same line item associated with the forecasted transactions and in the same period during which the hedged transactions affect earnings. See Note 11 to the Interim Condensed Consolidated Financial Statements for additional information. The assumptions used in measuring fair value of these interest rate derivatives are considered level 2 inputs, which are based upon observable market rates, including LIBOR and interest paid based upon a designated fixed rate over the life of the swap agreements.

Losses reclassified to earnings under these contracts were $4.4 million and $1.5 million for the three months ended January 31, 2021, and 2020, respectively. A derivative loss of $17.8 million, based upon interest rates at January 31, 2021, is expected to be reclassified from accumulated other comprehensive income (loss) to earnings in the next twelve months.

Foreign Exchange Hedges

The Company conducts business in various international currencies and is subject to risks associated with changing foreign exchange rates. The Company’s objective is to reduce volatility associated with foreign exchange rate changes. Accordingly, the Company enters into various contracts that change in value as foreign exchange rates change to protect the value of certain existing foreign currency assets and liabilities, commitments and anticipated foreign currency cash flows. As of January 31, 2021, and October 31, 2020, the Company had outstanding foreign currency forward contracts in the notional amount of $294.9 million and $268.6 million, respectively. Adjustments to fair value are recognized in earnings, offsetting the impact of the

hedged profits. The assumptions used in measuring fair value of foreign exchange hedges are considered level 2 inputs, which are based on observable market pricing for similar instruments, principally foreign exchange futures contracts.

Realized gains (losses) recorded in other expense, net under fair value contracts were $2.0 million and $(0.8) million for the three months ended January 31, 2021, and 2020, respectively. The Company recognized in other expense, net an unrealized net gain (loss) of $(0.6) million and $0.7 million during the three months ended January 31, 2021 and 2020, respectively.

Cross Currency Swap

The Company has operations and investments in various international locations and is subject to risks associated with changing foreign exchange rates. On March 6, 2018, the Company entered into a cross currency interest rate swap agreement that synthetically swaps $100.0 million of fixed rate debt to Euro denominated fixed rate debt at a rate of 2.35%. The agreement is designated as a net investment hedge for accounting purposes and will mature on March 6, 2023. Accordingly, the gain or loss on this derivative instrument is included in the foreign currency translation component of other comprehensive income until the net investment is sold, diluted or liquidated. Interest payments received for the cross currency swap are excluded from the net investment hedge effectiveness assessment and are recorded in interest expense, net on the interim condensed consolidated statements of income. For the three months ended January 31, 2021 and 2020, gains recorded in interest expense, net under the cross currency swap agreement were $0.6 million and $0.6 million, respectively. See Note 11 to the Interim Condensed Consolidated Financial Statements for additional information. The assumptions used in measuring fair value of the cross currency swap are considered level 2 inputs, which are based upon the Euro to United States Dollar exchange rate market.

Other Financial Instruments

The fair values of the Company’s 2019 Credit Agreement and the U.S. Receivables Facility and European RFA (the latter two facilities, collectively, "Accounts Receivable Credit Facilities") do not materially differ from carrying value as the Company’s cost of borrowing is variable and approximates current borrowing rates. The fair values of the Company’s long-term obligations are estimated based on either the quoted market prices for the same or similar issues or the current interest rates offered for the debt of the same remaining maturities, which are considered level 2 inputs in accordance with ASC Topic 820, "Fair Value Measurements and Disclosures."

The following table presents the estimated fair values of the Company’s Senior Notes and Assets held by special purpose entities:


(in millions)	January 31, 2021		October 31, 2020
Senior Notes due 2021 estimated fair value	$	249.8	$	242.0
Senior Notes due 2027 estimated fair value	533.8		524.4

STOCK-BASED COMPENSATION	3 Months Ended
STOCK-BASED COMPENSATION	Jan. 31, 2021
Share-based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION Long-Term Incentive Plan The Company's 2020 Long-Term Incentive Plan (the "2020 LTIP") is intended to focus management on the key measures that drive superior performance over the longer term. The 2020 LTIP provides key employees with incentive compensation based upon consecutive and overlapping three-year performance periods that commence at the start of every year. For each three-year performance period, the performance goals are based on performance criteria as determined by the Special Subcommittee of the Compensation Committee of the Company’s Board of Directors (the “Special Subcommittee”). For the three-year performance period commencing November 1, 2020, participants were granted restricted stock units (“RSUs”) or performance stock units (“PSUs”) or a combination of both. The Company grants RSUs based on a three-year vesting period on the basis of service only. The RSUs are an equity-classified plan measured at fair value on the grant date recognized ratably over the service period. Dividend-equivalent rights may be granted in connection with an RSU award and are recognized in conjunction with the Company's dividend issuance and settled upon vesting of the award. The Company granted 139,360 RSUs after plan approval on December 17, 2020, for the service period commencing on November 1, 2020 and ending October 31, 2023. The weighted average fair value of the RSUs granted on that date was $48.50. Under the 2020 LTIP, the Company grants PSUs for a three-year performance period based upon service, performance criteria and market conditions. The performance criteria are based on targeted levels of earnings before interest, taxes, depreciation, depletion and amortization and total shareholder return as determined by the Special Subcommittee. The PSUs are a liability-classified plan wherein the fair value of the PSUs awarded is determined at each reporting period using a Monte Carlo simulation. A Monte Carlo simulation uses assumptions including the risk-free interest rate, expected volatility of the Company’s stock price and expected life of the awards to determine a fair value of the market condition throughout the vesting period. The Company granted 253,102 PSUs after plan approval on December 17, 2020, for the performance period commencing on November 1, 2020 and ending October 31, 2023. If earned, the PSUs are to be awarded in shares of Class A Common Stock. The weighted average fair value of the PSUs granted on that date was $47.26. The weighted average fair value of the PSUs at January 31, 2021 was $46.80.

INCOME TAXES	3 Months Ended
INCOME TAXES	Jan. 31, 2021
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXESIncome tax expense for the quarter was computed in accordance with Accounting Standards Codification ("ASC") 740-270 "Income Taxes - Interim Reporting." Under this method, losses from jurisdictions for which a valuation allowance has been provided have not been included in the amount to which the ASC 740-270 rate was applied. Income tax expense of the Company may fluctuate due to changes in estimated losses and income from jurisdictions for which a valuation allowance has been provided, the timing of recognition of the related tax expense under ASC 740-270, and the impact of discrete items in the respective quarter.For the three months ended January 31, 2021 and January 31, 2020, income tax expense was $6.1 million and $11.4 million, respectively. The decrease in income tax expense for the three months ended January 31, 2021 was primarily caused by the reduction in pre-tax book earnings, greater tax credit utilization and a favorable one-time discrete item of $1.1 million for the settlement of the U.S. Federal Income tax audit in the period. Additionally, changes in judgement and lapses of statue of limitations for uncertain tax positions caused an increase to tax compared to first quarter of 2020.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

POST RETIREMENT BENEFIT PLANS

Postemployment Benefits [Abstract]

POST RETIREMENT BENEFIT PLANS

During the three months ended January 31, 2021, an annuity contract for approximately $100.0 million was purchased with United States defined benefit plan assets and the pension obligation for certain retirees in the United States under that plan was irrevocably transferred from that plan to the annuity contract. Additionally, lump sum payments totaling $1.5 million were made from the defined benefit plan assets to certain participants who agreed to such payments, representing the current fair value of the participant’s respective pension benefit. The settlement items described above resulted in a decrease in the fair value of both the plan assets and the projected benefit obligation of $101.5 million and a non-cash pension settlement charge of $8.5 million of unrecognized net actuarial loss included in accumulated other comprehensive loss.

As a result of the settlement described above, the Company remeasured the United States defined benefit pension plan as of November 30, 2020. The result of this remeasurement was a net increase of $20.8 million in the funded status of the plan. Plan assets increased $46.7 million due to higher than expected returns, which was partially offset by a $25.9 million increase in the projected benefit obligation due to a decrease in the discount rate from 3.01% as of October 31, 2020 to 2.76% as of November 30, 2020.

The components of net periodic pension cost include the following:


	Three Months Ended January 31,
(in millions)	2021		2020
Service cost	$	3.1	$	3.2
Interest cost	4.5		6.6
Expected return on plan assets	(7.9)		(10.3)
Amortization of prior service cost	—		3.5
Recognized net actuarial loss	3.8		—
Net periodic pension cost	$	3.5	$	3.0

As previously disclosed in the Company's Annual Report on Form 10-K for the year ended October 31, 2020, the Company expects to make employer contributions of $28.7 million, including benefits paid directly by the Company, during 2021.

The components of net periodic pension cost and net periodic post-retirement benefit, other than the service cost components, are included in the line item "Other expense, net" in the interim condensed consolidated statements of income.

CONTINGENT LIABILITIES AND ENVIRONMENTAL RESERVES	3 Months Ended
CONTINGENT LIABILITIES AND ENVIRONMENTAL RESERVES	Jan. 31, 2021
Environmental Remediation Obligations [Abstract]
CONTINGENT LIABILITIES AND ENVIRONMENTAL RESERVES	CONTINGENT LIABILITIES AND ENVIRONMENTAL RESERVES Litigation-related Liabilities The Company may become involved from time-to-time in litigation and regulatory matters incidental to its business, including governmental investigations, enforcement actions, personal injury claims, product liability, employment health and safety matters, commercial disputes, intellectual property matters, disputes regarding environmental clean-up costs, litigation in connection with acquisitions and divestitures, and other matters arising out of the normal conduct of its business. The Company intends to vigorously defend itself in such litigation. The Company does not believe that the outcome of any pending litigation will have a material adverse effect on its interim condensed consolidated financial statements. The Company may accrue for contingencies related to litigation and regulatory matters if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable resolutions can occur, assessing contingencies is highly subjective and requires judgments about future events. The Company regularly reviews contingencies to determine whether its accruals are adequate. The amount of ultimate loss may differ from these estimates. Since 2017, two reconditioning facilities in the Milwaukee, Wisconsin area that are owned by Container Life Cycle Management LLC ("CLCM"), the Company’s U.S. reconditioning joint venture company, have been subject to investigations conducted by federal, state and local governmental agencies concerning, among other matters, potential violations of environmental laws and regulations. As a result of these investigations, the United States Environmental Protection Agency (“U.S. EPA”) and the Wisconsin Department of Natural Resources (“WDNR”) have issued notices of violations to the Company and CLCM regarding violations of certain federal and state environmental laws and regulations. The remedies being sought in these proceedings include compliance with the applicable environmental laws and regulations as being interpreted by the U.S. EPA and WDNR and monetary sanctions. The Company has cooperated with the governmental agencies in these investigations and proceedings. As of February 26, 2021, no material citations have been issued or material fines assessed with respect to any violation of environmental laws and regulations. Since these proceedings remain in their investigative stage, the Company is unable to predict the outcome of these proceedings or estimate a range of reasonable possible monetary sanctions or costs associated with any remedial actions that may be required or requested by the U.S. EPA or WDNR. In addition, on November 8, 2017, the Company, CLCM and other parties were named as defendants in a punitive class action lawsuit filed in Wisconsin state court concerning one of CLCM’s Milwaukee reconditioning facilities. The plaintiffs are alleging that odors from this facility have invaded their property and are interfering with the use and enjoyment of their property and causing damage to the value of their property. Plaintiffs are seeking compensatory and punitive damages, along with their legal fees. The Company and CLCM are vigorously defending themselves in this lawsuit. The Company is unable to predict the outcome of this lawsuit or estimate a range of reasonably possible losses. Environmental Reserves As of January 31, 2021, and October 31, 2020, the Company's environmental reserves were $19.7 million and $20.2 million, respectively. These reserves are principally based on environmental studies and cost estimates provided by third parties, but also take into account management estimates. The estimated liabilities are reduced to reflect the anticipated participation of other potentially responsible parties in those instances where it is probable that such parties are legally responsible and financially capable of paying their respective shares of relevant costs. For sites that involve formal actions subject to joint and several liabilities, these actions have formal agreements in place to apportion the liability. As of January 31, 2021 and October 31, 2020, the Company has accrued $11.1 million for the Diamond Alkali Superfund Site in New Jersey. It is possible that there could be resolution of uncertainties in the future that would require the Company to record charges that could be material to future earnings. Aside from the Diamond Alkali Superfund Site, other environmental reserves of the Company as of January 31, 2021 and October 31, 2020 included $8.6 million and $9.1 million, respectively, for its various facilities around the world. The Company’s exposure to adverse developments with respect to any individual site is not expected to be material. Although environmental remediation could have a material effect on results of operations if a series of adverse developments occur in a particular quarter or year, the Company believes that the chance of a series of adverse developments occurring in the same quarter or year is remote. Future information and developments will require the Company to continually reassess the expected impact of these environmental matters.

EARNINGS PER SHARE

3 Months Ended

Jan. 31, 2021

Earnings Per Share [Abstract]

EARNINGS PER SHARE

The Company has two classes of common stock and, as such, applies the “two-class method” of computing earnings per share (“EPS”) as prescribed in ASC 260, “Earnings Per Share.” In accordance with this guidance, earnings are allocated in the same fashion as dividends would be distributed. Under the Company’s certificate of incorporation, any distribution of dividends in any year must be made in proportion of one cent a share for Class A Common Stock to one and one-half cents a share for Class B Common Stock, which results in a 40% to 60% split to Class A and B shareholders, respectively. In accordance with this, earnings are allocated first to Class A and Class B Common Stock to the extent that dividends are actually paid and the remainder is allocated assuming all of the earnings for the period have been distributed in the form of dividends.

The Company calculates EPS as follows:

Basic Class A EPS

=

40% * Average Class A Shares Outstanding

*

Undistributed Net Income

+

Class A Dividends Per Share

40% * Average Class A Shares Outstanding + 60% * Average Class B Shares Outstanding

Average Class A Shares Outstanding

Diluted Class A EPS

Class A Dividends Per Share

40% * Average Class A Shares Outstanding + 60% * Average Class B Shares Outstanding

60% * Average Class B Shares Outstanding

*

Undistributed Net Income

+

Class B Dividends Per Share

40% * Average Class A Shares Outstanding + 60% * Average Class B Shares Outstanding

Average Class B Shares Outstanding

*Diluted Class B EPS calculation is identical to Basic Class B calculation

The following table provides EPS information for each period, respectively:


	Three Months Ended January 31,
(in millions)	2021		2020
Numerator for basic and diluted EPS
Net income attributable to Greif, Inc.	$	23.4	$	32.3
Cash dividends	(25.9)		(25.9)
Undistributed earnings attributable to Greif, Inc.	$	(2.5)	$	6.4

The Class A Common Stock has no voting rights unless four quarterly cumulative dividends upon the Class A Common Stock are in arrears. The Class B Common Stock has full voting rights. There is no cumulative voting for the election of directors.

Common Stock Repurchases

The Board of Directors has authorized the Company to repurchase shares of the Company's Class A Common Stock or Class B Common Stock or any combination of the foregoing. As of January 31, 2021, the remaining amount of shares that may be repurchased under this authorization was 4,703,487. There were no shares repurchased during the first quarter of 2021 or fiscal year 2020.

The following table summarizes the Company’s Class A and Class B common and treasury shares as of the specified dates:


	Authorized Shares	Issued Shares	Outstanding Shares	Treasury Shares

LEASES

Jan. 31, 2021

Leases [Abstract]

LEASES

The Company leases certain buildings, warehouses, land, transportation equipment, operating equipment, and office equipment with remaining lease terms from less than one year up to 21 years. The Company reviews all options to extend, terminate, or purchase a right of use asset at the time of lease inception and accounts for options deemed reasonably certain.

The Company combines lease and non-lease components for all leases, except real estate, for which these components are presented separately. Leases with an initial term of twelve months or less are not capitalized and are recognized on a straight-line basis over the lease term. The implicit rate is not readily determinable for substantially all of the Company's leases, and therefore the initial present value of lease payments is calculated utilizing an estimated incremental borrowing rate determined at the portfolio level based on market and Company specific information.

Certain of the Company’s leases include variable costs. As the right of use asset recorded on the balance sheet was determined based upon factors considered at the commencement date, changes in these variable expenses are not capitalized and are expensed as incurred throughout the lease term.

As of January 31, 2021, the Company does not have material exposure to finance leases and has not entered into any significant leases which have not yet commenced.

The following table presents the lease expense components for the three months ended January 31, 2021 and 2020:


	Three Months Ended January 31,

Segment Reporting [Abstract]

BUSINESS SEGMENT INFORMATION

The Company has made changes to the operational and financial management practices and procedures of the Rigid Industrial Packaging & Services and Flexible Products & Services segments and combined the two segments under a single global leadership team. These changes were made to enhance cross-selling and service offerings to customers within similar markets and enhance Greif Business System effectiveness. As a result of these changes, during the first quarter of 2021, the Rigid Industrial Packaging & Services reportable segment and the Flexible Products & Services reportable segment have been combined into a single reportable segment known as Global Industrial Packaging. On February 24, 2021, the Company filed a Current Report on Form 8-K with the SEC to furnish certain historical GAAP and non-GAAP financial information in a revised presentation aligned with the Company's new reportable segment structure described above.

The Company’s reportable business segments offer different products and services and are compiled of six operating segments. The accounting policies of the reportable business segments are substantially the same as those described in the “Basis of Presentation and Summary of Significant Accounting Policies” note in the 2020 Form 10-K.

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Jan. 31, 2021
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The interim condensed consolidated financial statements have been prepared in accordance with the U.S. Securities and Exchange Commission (“SEC”) instructions to Quarterly Reports on Form 10-Q and include all of the information and disclosures required by accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting. The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the interim condensed consolidated financial statements and accompanying notes. Actual amounts could differ from those estimates. The fiscal year of Greif, Inc. and its subsidiaries (the “Company”) begins on November 1 and ends on October 31 of the following year. Any references to years or to any quarter of those years, relates to the fiscal year or quarter, as the case may be, ended in that year, unless otherwise stated. The information filed herein reflects all adjustments that are, in the opinion of management, necessary for a fair presentation of the interim condensed consolidated balance sheets as of January 31, 2021 and October 31, 2020, the interim condensed consolidated statements of income and comprehensive income for the three months ended January 31, 2021 and 2020 and the interim condensed consolidated statements of cash flows for the three months ended January 31, 2021 and 2020 of the Company. The interim condensed consolidated financial statements include the accounts of Greif, Inc., all wholly-owned and consolidated subsidiaries and investments in limited liability companies, partnerships and joint ventures in which it has controlling influence or is the primary beneficiary. Non-majority owned entities include investments in limited liability companies, partnerships and joint ventures in which the Company does not have controlling influence and are accounted for using either the equity or cost method, as appropriate. The unaudited interim condensed consolidated financial statements included in the Quarterly Report on Form 10-Q (this “Form 10-Q”) should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for its fiscal year ended October 31, 2020 (the “2020 Form 10-K”). Effective the first quarter 2021, the Company adjusted its reportable segments. The presentation of prior periods throughout Part I Item 1 of this Form 10-Q has been modified to reflect the new segment reporting structure. See Note 12 to the Interim Condensed Consolidated Financial Statements for additional information. COVID-19 The preparation of financial statements requires management to make estimates and assumptions that affect the amounts of assets, liabilities, revenues and expenses reported in such financial statements. The estimates and assumptions used in the preparation of the financial statements contained in this Form 10-Q do not reflect material changes to the estimates and assumptions disclosed in the 2020 Form 10-K. Nevertheless, the Company's actual results and outcomes during the three months ended January 31, 2021 have been impacted by the COVID-19 pandemic, which has caused market disruption and volatility. Because the scope, duration and magnitude of the effects of the COVID-19 pandemic continue to evolve, the Company cannot, at this time, predict the impact the pandemic will have on its future consolidated financial position, cash flows or results of operations; however, the impact could be material. The Company's future financial results and operations depend in part on the duration and severity of the pandemic and what actions are taken to mitigate the outbreak.
Newly Adopted Accounting Standards and Recently Issued Accounting Standards	Newly Adopted Accounting Standards In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, “Financial Instruments – Credit Losses.” This ASU sets forth a current expected credit loss model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. The Company adopted this ASU on November 1, 2020. The adoption of this guidance did not have a material impact on financial position, results of operations, comprehensive income, cash flows or disclosures. Recently Issued Accounting Standards In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes", which is intended to simplify accounting for income taxes. This ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years, with early adoption permitted. The effective date for the Company to adopt this ASU is November 1, 2021. The Company is in the process of determining the potential impact of adopting this guidance on its financial position, results of operations, comprehensive income, cash flow and disclosures.
