Explanatory Note

This Form 8-K/A amends the Report on Form 8-K filed by Greif, Inc. (the “Company”) on July 8, 2014 (the “Initial Form 8-K”), regarding the resignation of Ernst & Young LLP (“EY”) as the Company’s independent registered public accounting firm. This Form 8-K/A contains information concerning the engagement by the Company’s Audit Committee (the “Audit Committee”) of Deloitte & Touche LLP (“Deloitte”) as the Company’s new independent registered public accounting firm to audit the Company’s financial statements for its fiscal year ending October 31, 2014, and the effectiveness of the Company’s internal control over financial reporting as of October 31, 2014.

EY’s resignation will become effective after the Company files its Form 10-Q for its fiscal quarter ending July 31, 2014, which the Company anticipates filing on or about August 29, 2014. At that time, the Company will further amend the Initial Form 8-K to provide the disclosures required by Item 4.01(a) through the effective date of EY’s resignation.

Section 4 – Matters Related to Accountants and Financial Statements

Item 4.01 Changes in Registrant’s Certifying Accountant.

In selecting a new auditor, the Company engaged in a competitive bid process and solicited requests for proposals from five large accounting firms that the Audit Committee believed might be able to serve as auditor for a company with the size and complexity of the Company. The Audit Committee then engaged in a rigorous evaluation process, with its selection criteria focused on each firms’ respective global presence and resources in countries outside the United States so as to evaluate whether the firm would be in a position to effectively audit the Company’s financial statements. The Audit Committee also carefully considered, among other things, the strength and relevant experience of the primary engagement team, knowledge of the Company and the types of risks it confronts, and the strength of the firm’s national office and risk management functions. The Audit Committee observed that while other firms might have qualifications to serve as the Company’s auditor, independence or resource matters arose with respect to those firms. In selecting Deloitte, the Audit Committee determined that Deloitte is best qualified to serve as the Company’s auditor because of its extensive experience with large U.S. multinational companies and the strength of the engagement team.

As part of the engagement process, the Company and Deloitte identified certain non-audit services that Deloitte (or another firm in its global network of firms) performed for the Company during its 2014 fiscal year that are not permitted under the SEC’s auditor independence rules. The Audit Committee and Deloitte discussed these non-audit services and concluded that the provision of these non-audit services will not affect Deloitte’s objectivity or its impartiality and will not impair its ability to serve as the Company’s independent registered accounting firm.

The services that Deloitte or another firm in Deloitte’s global network of firms previously performed for the Company during fiscal year 2014 were as follows:

During the Company’s two most recent fiscal years ended October 31, 2013 and 2012 and prior to engaging Deloitte on August 26, 2014, neither the Company nor anyone on its behalf consulted Deloitte regarding either: (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, in connection with which either a written report or oral advice was provided to the Company that Deloitte concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a disagreement or reportable event as defined in Regulation S-K, Item 304(a)(1)(iv) and Item 304(a)(1)(v), respectively.
