Exhibit 99.3

Unaudited Pro Forma Condensed Combined Financial Information

The following unaudited pro forma condensed combined financial information presents the unaudited pro forma condensed combined statements of income based upon the combined historical financial statements of Korn/Ferry International, a Delaware corporation (together with its subsidiaries, “we”, “us”, “our”, the “Company”, or “Korn/Ferry”) and HG (Luxembourg) S.à.r.l., a private limited liability company organized under the laws of Luxembourg (“Hay Group”), after giving effect to our purchase of all the issued and outstanding shares and non-interest bearing convertible preferred equity certificates of Hay Group (the “Hay Group Acquisition”, or “Acquisition”), discussed in detail below, and are intended to reflect the impact of the Hay Group Acquisition on Korn/Ferry on a pro forma basis as of and for the periods indicated. Korn/Ferry’s historical financial and operating data for the year ended April 30, 2015 and the three-month period ended July 31, 2015 is derived from the financial data in its audited consolidated financial statements for the year ended April 30, 2015 and from its unaudited consolidated financial statements for the three-month period ended July 31, 2015. The historical financial and operating data for Hay Group for the twelve months ended March 31, 2015 is derived by adding the financial data from Hay Group’s audited consolidated statement of income for the year ended September 30, 2014 and Hay Group’s unaudited condensed consolidated statement of income for the six-month period ended March 31, 2015, and subtracting Hay Group’s unaudited condensed consolidated statement of income for the six-month period ended March 31, 2014. The historical financial and operating data for Hay Group for the three-month period ended June 30, 2015 is derived by subtracting the financial data from Hay Group’s unaudited condensed consolidated statements of income for the six-month period ended March 31, 2015 from Hay Group’s unaudited condensed consolidated statement of income for the nine-month period ended June 30, 2015. In the remainder of this document, we collectively refer to Korn/Ferry and Hay Group, subsequent to the Hay Group Acquisition, as “the Combined Company.”

The unaudited pro forma condensed combined balance sheet as of July 31, 2015 shows the combined financial position of Korn/Ferry and Hay Group as if the Acquisition had occurred on July 31, 2015. The unaudited pro forma condensed combined statements of income for the year ended April 30, 2015 and the three months ended July 31, 2015 reflect the Acquisition as if it had occurred on May 1, 2014, the beginning of the earliest period presented. This unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting, with Korn/Ferry considered the acquirer of Hay Group for accounting purposes.

The unaudited pro forma condensed combined financial information was prepared in accordance with Article 11 of Regulation S-X. The unaudited pro forma adjustments reflecting the Acquisition have been prepared in accordance with business combination accounting guidance as provided in Accounting Standards Codification 805, Business Combinations, and reflect the preliminary allocation of the purchase price to the acquired assets and liabilities based upon a preliminary estimate of fair values, using the assumptions set forth in the notes to the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information is based upon, and should be read in conjunction with:

We have prepared the unaudited pro forma condensed combined financial information to reflect adjustments to our historical consolidated financial information that are (i) directly attributable to the Hay Group Acquisition, (ii) factually supportable and (iii) with respect to the unaudited pro forma condensed combined statement of income, expected to have a continuing impact on the Combined Company’s results.

We present the unaudited pro forma condensed combined financial information for informational purposes only. Such information is not necessarily indicative of the operating results or financial position that actually would have been achieved if we had consummated the Hay Group Acquisition on the dates indicated or that the Combined Company may achieve in future periods; it also does not reflect any cost savings, operating synergies or revenue enhancements that the Combined Company may achieve, costs to integrate the business or the impact of any non-recurring activity and any one-time, transaction-related costs. We have excluded synergies and integration costs from consideration because they do not meet the criteria for unaudited pro forma adjustments.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

On December 1, 2015, we completed the acquisition of all the issued and outstanding shares and non-interest bearing convertible preferred equity certificates of Hay Group. Following the closing of the Hay Group Acquisition (the “Closing”), Hay Group became an indirect wholly owned subsidiary of the Company.

Under the terms of the Stock Purchase Agreement, dated as of September 23, 2015 (the “Purchase Agreement”), by and between HG (Bermuda) Limited (“Seller”) and Korn/Ferry, we paid Seller an aggregate purchase price of approximately $470.5 million, consisting of (a) approximately $252.6 million in cash, net of acquired cash and after giving effect to purchase price adjustments as described in the Purchase Agreement, and (b) 5,922,136 shares of our common stock, par value $0.01 per share, representing an aggregate value of $217.9 million based on the closing price of our common stock on The New York Stock Exchange on November 30, 2015. We have also committed to a retention pool of approximately $40.0 million for certain employees of Hay Group subject to certain circumstances.

We funded the cash portion of the Hay Group Acquisition in part by borrowing a $150.0 million senior unsecured delayed draw term loan facility (the “Term Facility”) under the existing Credit Agreement dated as of January 18, 2013 by and among Korn/Ferry, as borrower, and Wells Fargo Bank, National Association, as lender (the “Lender”), as amended on September 23, 2015.

Prior to the Closing, Korn/Ferry and Seller entered into a letter agreement, dated November 30, 2015 (the “SPA Letter Agreement”), to provide for, among other things, the acquisition by Korn/Ferry Canada, Inc., a corporation organized under the laws of Canada and an indirect wholly owned subsidiary of Korn/Ferry, of all the issued and outstanding capital stock of Hay Group Ltd., a corporation organized under the laws of Ontario, Canada and an indirect wholly owned subsidiary of Seller, from Hay Group Investment Holding B.V., a private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) organized under the laws of the Netherlands and an indirect wholly owned subsidiary of Seller (the “Hay Canada Share Acquisition”), immediately prior to the consummation of the Acquisition.

Basis of Presentation

The unaudited pro forma condensed combined financial information should be read in conjunction with the audited and unaudited consolidated financial statements of Hay Group included elsewhere in the Current Report on Form 8-K/A of which this financial information forms an exhibit, as well as our audited and unaudited consolidated financial statements and the related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in our Annual Report on Form 10-K for the fiscal year ended April 30, 2015 and in our Quarterly Report on Form 10-Q for the quarterly period ended July 31, 2015.

The unaudited pro forma condensed combined financial information included herein has been prepared pursuant to the rules and regulations of the SEC. Pursuant to such rules and regulations, we have condensed or omitted certain information and certain footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles; however, management believes that the disclosures are adequate to make the information presented not misleading.

The fair value of consideration transferred on the closing date includes the value of the cash consideration, the fair value of the equity transferred as part of the acquisition, and Hay Group’s historical cash. The purchase price is as follows (in thousands, except shares and per share stock price):

Preliminary Purchase Price Allocation

Under the acquisition method of accounting, the identifiable assets acquired and liabilities assumed of Hay Group are recorded at the acquisition date fair values and added to those of Korn/Ferry. The pro forma adjustments are preliminary and based on estimates of the fair value and useful lives of the assets acquired and liabilities assumed as of December 1, 2015 and have been prepared to illustrate the estimated effect of the Acquisition. The allocation is dependent upon certain valuation and other studies that have not yet been completed. Accordingly, the pro forma purchase price allocation is subject to further adjustment as additional information becomes available and as additional analyses and final valuations are completed. There can be no assurances that these additional analyses and final valuations will not result in significant changes to the estimates of fair value set forth below.

The following table sets forth a preliminary allocation of the purchase consideration to the identifiable tangible and intangible assets acquired and liabilities assumed of Hay Group based on Hay Group’s June 30, 2015 balance sheet, with the excess recorded as goodwill (in thousands):

Preliminary identifiable intangible assets in the pro forma financial statements consist of anticipated intangibles derived from intellectual property, customer relationships, and tradename. The amortization related to these amortizable identifiable intangible assets is reflected as a pro forma adjustment to the pro forma statements of income, as further described in Note 7.

The deferred income taxes, net and deferred tax liabilities included in other liabilities above primarily represent the tax effect on the amortizable identifiable intangibles as amortization of such intangibles will not be deductible for tax purposes.

7

Goodwill represents the excess of the purchase price over the fair value of the underlying net assets. Goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually, absent any indicators of impairment. Goodwill recognized in the Acquisition is not expected to be deductible for tax purposes.

The amounts above are considered preliminary and are subject to change once the Company receives certain information it believes is necessary to finalize its determination of the fair value of assets acquired and liabilities assumed under the acquisition method. Thus these amounts are subject to refinement, and additional adjustments to record fair value of all assets acquired and liabilities assumed may be required.

Upon consummation of the Hay Group Acquisition, Hay Group adopted our accounting policies. We performed certain procedures for the purpose of identifying any material differences in significant accounting policies between Korn/Ferry and Hay Group, and any accounting adjustments that would be required in connection with adopting uniform policies and disclosures. Procedures performed involved a review of Hay Group’s summary of significant accounting policies, including those disclosed in Hay Group’s historical audited financial statements for the year ended September 30, 2014 and historical unaudited financial statements for the nine months ended June 30, 2015, and preliminary discussions with Hay Group management regarding Hay Group’s significant accounting policies to identify material adjustments. We expect to engage in additional review of the policies and discussion with Hay Group’s management to continue to evaluate the impact of Hay Group’s accounting policies on its historical results. Additionally, the historical consolidated financial statements of Hay Group presented herein have been adjusted by condensing certain line items and by reclassifying certain line items in order to conform to Korn/Ferry’ financial statement presentation; these reclassifications are reflected in the column “Accounting Policies and Reclassifications.”

The reclassification adjustments on the unaudited pro forma balance sheet pertain to the following:

The significant intangible assets identified in the preliminary purchase price allocation discussed above include intellectual property, customer relationships, and tradename. The table below indicates the estimated fair value of each of the intangibles identified and the approximate useful lives of each (in thousands):

Fair value was estimated using inputs primarily from the income approach. The income approach included the use of both the relief from royalties method and the multiple period excess earnings method. The significant assumptions used in estimating fair value included (i) the estimated life the asset will contribute to cash flows, such as attrition rate of customers or remaining contractual terms, (ii) the estimated discount rate that reflects the level of risk associated with receiving future cash flows, (iii) profitability, and (iv) the royalty rate used.

On September 23, 2015, the Company entered into Amendment No. 3 (the “Amendment No. 3”) to the existing Credit Agreement dated as of January 18, 2013 with the Lender, as previously amended by Amendment No. 1 dated as of December 12, 2014 (the “Amendment No. 1”) and Amendment No. 2 dated as of June 3, 2015 (the “Amendment No. 2”) (the existing Credit Agreement, as amended by the Amendment No. 1, the Amendment No. 2, and the Amendment No. 3, the “Credit Agreement”).

13

The Amendment No. 3 provides for, among other things: (i) the Term Facility; (ii) a reduction in the revolving credit facility (the “Revolver” and, together with the Term Facility, the “Credit Facilities”) from an aggregate principal amount of $150 million to $100 million; (iii) an extension to the maturity date of the Revolver; (iv) consent to enter into the acquisition of Hay Group; (v) certain changes to affirmative and negative covenants, including an increase to the minimum adjusted EBITDA that the Company must maintain from $70 million to $100 million, (vi) an increase in the amount of permitted acquisitions, paying dividends to stockholders and making share repurchases in any fiscal year from $125.0 million to $135.0 million (excluding the recently announced acquisition of Hay Group); and (vii) an increase in the amount of dividends paid to stockholders and share repurchases in any fiscal year from $75.0 million to $85.0 million (excluding the recently announced acquisition of Hay Group).

At the Company’s option, loans issued under the Credit Facilities will bear interest at either adjusted LIBOR or an alternate base rate, in each case plus the applicable interest rate margin. The interest rate applicable to loans outstanding under the Credit Facilities may fluctuate between adjusted LIBOR plus 1.125% per annum to adjusted LIBOR plus 1.875% per annum, in the case of LIBOR borrowings (or between the alternate base rate plus 0.125% per annum and the alternate base rate plus 0.875% per annum, in the alternative), based upon the Company’s total funded debt to adjusted EBITDA ratio (as set forth in the Credit Agreement, the “consolidated leverage ratio”) at such time. In addition, the Company will be required to pay to the Lender a quarterly fee ranging from 0.25% to 0.40% per annum on the average daily unused amount of the Credit Facilities, based upon the Company’s consolidated leverage ratio at such time, and fees relating to the issuance of letters of credit.

Both the Revolver and the Term Facility mature on September 23, 2020, and may be prepaid and terminated early by the Company at any time without premium or penalty (subject to customary LIBOR breakage fees).

A sensitivity analysis on interest expense for the year ended April 30, 2015 and the three month period ended July 31, 2015 has been performed to assess the effect of a change of 12.5 basis points of the hypothetical interest rate would have on the debt financing.

The following table shows interest expense for the debt financing assuming a change in the interest rate (in thousands):
