Organization and Summary of Significant Accounting Policies	1. Organization and Summary of Significant Accounting Policies Nature of Business Korn/Ferry International, a Delaware corporation (the “Company”), and its subsidiaries are engaged in the business of providing talent management solutions, including executive search on a retained basis, recruitment for non-executive Basis of Consolidation and Presentation The accompanying financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K Investments in affiliated companies, which are 50% or less owned and where the Company exercises significant influence over operations, are accounted for using the equity method. The Company has control of a Mexico subsidiary and consolidates the operations of this subsidiary. Noncontrolling interest, which represents the Company’s 51% noncontrolling interest in the Mexico subsidiary, is reflected on the Company’s consolidated financial statements. The Company considers events or transactions that occur after the balance sheet date but before the consolidated financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosures. Use of Estimates and Uncertainties The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates and changes in estimates are reported in current operations as new information is learned or upon the amounts becoming fixed and determinable. The most significant areas that require management judgment are revenue recognition, restructuring, deferred compensation, annual performance related bonuses, evaluation of the carrying value of receivables, goodwill and other intangible assets, fair value of contingent consideration, share-based payments and the recoverability of deferred income taxes. Revenue Recognition Substantially all fee revenue is derived from fees for professional services related to executive search performed on a retained basis, recruitment for non-executive non-executive one-third non-executive non-executive Depending on the timing of billings and services rendered, the Company accrues or defers revenue as appropriate. Hay Group revenue is also derived from the sale of product services, which includes revenue from licenses and from the sale of products. Revenue from licenses is recognized using a straight-line method over the term of the contract (generally 12 months). Under fixed term licenses, the Company is obligated to provide the licensee with access to any updates to the underlying intellectual property that are made by the Company during the term of the license. Once the term of the agreement expires, the client’s right to access or use the intellectual property expires and the Company has no further obligations to the client under the license agreement. Revenue from perpetual licenses is recognized when the license is sold since the Company’s only obligation is to provide the client access to the intellectual property but is not obligated to provide maintenance, support, updates or upgrades. Products sold by the Company mainly consist of books and automated services covering a variety of topics including performance management, team effectiveness, and coaching and development. The Company recognizes revenue for its products when the product has been sold or shipped in the case of books. As of October 31, 2017 and April 30, 2017, the Company included deferred revenue of $100.2 million and $95.8 million, respectively, in other accrued liabilities. Reimbursements The Company incurs certain out-of-pocket Allowance for Doubtful Accounts An allowance is established for doubtful accounts by taking a charge to general and administrative expenses. The amount of the allowance is based on historical loss experience, assessment of the collectability of specific accounts, as well as expectations of future collections based upon trends and the type of work for which services are rendered. After the Company exhausts all collection efforts, the amount of the allowance is reduced for balances identified as uncollectible. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. As of October 31, 2017 and April 30, 2017, the Company’s investments in cash equivalents consist of money market funds for which market prices are readily available. Marketable Securities The Company currently has investments in mutual funds that are classified as trading securities based upon management’s intent and ability to hold, sell or trade such securities. The classification of the investments in mutual funds is assessed upon purchase and reassessed at each reporting period. The investments in mutual funds (for which market prices are readily available) are held in trust to satisfy obligations under the Company’s deferred compensation plans. Such investments are based upon the employees’ investment elections in their deemed accounts in the Executive Capital Accumulation Plan and similar plans in Asia Pacific and Canada (“ECAP”) from a pre-determined ex-dividend Fair Value of Financial Instruments Fair value is the price the Company would receive to sell an asset or transfer a liability (exit price) in an orderly transaction between market participants. For those assets and liabilities recorded or disclosed at fair value, the Company determines the fair value based upon the quoted market price, if available. If a quoted market price is not available for identical assets, the fair value is based upon the quoted market price of similar assets. The fair values are assigned a level within the fair value hierarchy as defined below: ◾ Level 1: ◾ Level 2: ◾ Level 3: As of October 31, 2017 and April 30, 2017, the Company held certain assets that are required to be measured at fair value on a recurring basis. These included cash, cash equivalents, accounts receivable, marketable securities, foreign currency forward contracts and interest rate swap. The carrying amount of cash, cash equivalents and accounts receivable approximates fair value due to the short maturity of these instruments. The fair values of marketable securities classified as trading are obtained from quoted market prices and the fair values of foreign currency forward contracts or the interest rate swap are obtained from a third party, which are based on quoted prices or market prices for similar assets and financial instruments. Derivative Financial Instruments The Company is exposed to interest rate risk due to the outstanding senior secured credit agreement entered on June 15, 2016. The Company has entered into an interest rate swap agreement to effectively convert its variable debt to a fixed-rate basis. The principal objective of these contracts is to eliminate or reduce the variability of the cash flows in interest payments associated with the Company’s long-term debt, thus reducing the impact of interest rate changes on future interest payment cash flows. The Company has determined that the interest rate swap qualifies as a cash flow hedge in accordance with Accounting Standards Codification 815, Derivatives and Hedging Foreign Currency Forward Contracts Not Designated as Hedges The Company has established a program that primarily utilizes foreign currency forward contracts to offset the risks associated with the effects of certain foreign currency exposures. These foreign currency forward contracts are neither used for trading purposes nor are they designated as hedging instruments pursuant to Accounting Standards Codification 815, Derivatives and Hedging Business Acquisitions Business acquisitions are accounted for under the acquisition method. The acquisition method requires the reporting entity to identify the acquirer, determine the acquisition date, recognize and measure the identifiable assets acquired, the liabilities assumed and any noncontrolling interest in the acquired entity and recognize and measure goodwill or a gain from the purchase. The acquiree’s results are included in the Company’s consolidated financial statements from the date of acquisition. Assets acquired and liabilities assumed are recorded at their fair values and the excess of the purchase price over the amounts assigned is recorded as goodwill, or if the fair value of the assets acquired exceeds the purchase price consideration, a bargain purchase gain is recorded. Adjustments to fair value assessments are generally recorded to goodwill over the measurement period (not longer than twelve months). The acquisition method also requires that acquisition-related transaction and post-acquisition restructuring costs be charged to expense as committed and requires the Company to recognize and measure certain assets and liabilities including those arising from contingencies and contingent consideration in a business combination. Goodwill and Intangible Assets Goodwill represents the excess of the purchase price over the fair value of assets acquired. The goodwill impairment test compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, goodwill of the reporting unit would be considered impaired. To measure the amount of the impairment loss, the implied fair value of a reporting unit’s goodwill is compared to the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. If the carrying amount of a reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. For each of these tests, the fair value of each of the Company’s reporting units is determined using a combination of valuation techniques, including a discounted cash flow methodology. To corroborate the discounted cash flow analysis performed at each reporting unit, a market approach is utilized using observable market data such as comparable companies in similar lines of business that are publicly traded or which are part of a public or private transaction (to the extent available). Results of the annual impairment test performed as of January 31, 2017, indicated that the fair value of each reporting unit exceeded its carrying amount and no reporting units were at risk of failing the impairment test. As a result, no impairment charge was recognized. There was also no indication of potential impairment as of October 31, 2017 and April 30, 2017 that would have required further testing. Intangible assets primarily consist of customer lists, non-compete Compensation and Benefits Expense Compensation and benefits expense in the accompanying consolidated statements of income consist of compensation and benefits paid to consultants (employees who originate business), executive officers and administrative and support personnel. The most significant portions of this expense are salaries and the amounts paid under the annual performance related bonus plan to employees. The portion of the expense applicable to salaries is comprised of amounts earned by employees during a reporting period. The portion of the expenses applicable to annual performance related bonuses refers to the Company’s annual employee performance related bonus with respect to a fiscal year, the amount of which is communicated and paid to each eligible employee following the completion of the fiscal year. Each quarter, management makes its best estimate of its annual performance related bonuses, which requires management to, among other things, project annual consultant productivity (as measured by engagement fees billed and collected by executive search consultants and revenue and other performance/profitability metrics for Hay Group and Futurestep consultants), the level of engagements referred by a consultant in one line of business to a different line of business, Company performance including profitability, competitive forces and future economic conditions and their impact on the Company’s results. At the end of each fiscal year, annual performance related bonuses take into account final individual consultant productivity (including referred work), Company/line of business results including profitability, the achievement of strategic objectives, the results of individual performance appraisals and the current economic landscape. Accordingly, each quarter the Company reevaluates the assumptions used to estimate annual performance related bonus liability and adjusts the carrying amount of the liability recorded on the consolidated balance sheet and reports any changes in the estimate in current operations. Because annual performance-based bonuses are communicated and paid only after the Company reports its full fiscal year results, actual performance-based bonus payments may differ from the prior year’s estimate. Such changes in the bonus estimate historically have been immaterial and are recorded in current operations in the period in which they are determined. The performance related bonus expense was $98.5 million and $95.1 million during the six months ended October 31, 2017 and 2016, respectively, included in compensation and benefits expense in the consolidated statements of income. During the three months ended October 31, 2017 and 2016, the performance related bonus expense was $56.9 million and $52.7 million, respectively. Other expenses included in compensation and benefits expense are due to changes in deferred compensation and pension plan liabilities, changes in cash surrender value (“CSV”) of company owned life insurance (“COLI”) contracts, amortization of stock compensation awards, payroll taxes and employee insurance benefits. Investments and other assets include long-term retention awards that are generally amortized over four to five years. Restructuring Charges, Net The Company accounts for its restructuring charges as a liability when the obligations are incurred and records such charges at fair value. Such charges included one-time Stock-Based Compensation The Company has employee compensation plans under which various types of stock-based instruments are granted. These instruments principally include restricted stock units, restricted stock, stock options and an Employee Stock Purchase Plan (“ESPP”). The Company recognizes compensation expense related to restricted stock units, restricted stock and the estimated fair value of stock options and stock purchases under the ESPP on a straight-line basis over the service period for the entire award. Recently Adopted Accounting Standards In March 2016, the Financial Accounting Standards Board (the “FASB”) issued guidance on accounting for certain aspects of share-based payments to employees. The new guidance requires excess tax benefits and tax deficiencies to be recorded in the income statement when the awards vest or are settled. Furthermore, cash flows related to excess tax benefits will no longer be separately classified as a financing activity apart from other income tax cash flows. The guidance also allows companies to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting, clarifying that all cash payments made on an employee’s behalf for withheld shares should be presented as a financing activity in the consolidated statements of cash flows and provides an accounting policy election to account for forfeitures as they occur. The provisions of the guidance are effective for fiscal years beginning after December 15, 2016 and were adopted by the Company effective May 1, 2017. The primary impact of the adoption was the recognition of excess tax benefits in our provision for income taxes in the current year compared to recording it previously as a component of equity. Additional amendments to the accounting for income taxes and minimum statutory withholding tax requirements had no impact to retained earnings, where the cumulative effect of these changes are required to be recorded. The Company elected to apply the presentation for cash flows related to excess tax benefits retrospectively for all periods presented which resulted in minimal impact to cash used in operations and cash provided by financing activities for the six months ended October 31, 2016. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact on any of the periods presented on our consolidated cash flows statements since such cash flows have historically been presented as a financing activity. The Company elected to account for forfeitures as they occur, rather than estimating the expected forfeitures over the vesting period. This election did not have an impact on the Company’s financial statements. Recently Proposed Accounting Standards In May 2014, the FASB issued ASU 2014-09, 2014-09: The new guidance is effective for fiscal years and interim periods within those annual years beginning after December 15, 2017. The Company will adopt this guidance in its fiscal year beginning May 1, 2018 and expects to apply the modified retrospective method in adopting ASU 2014-09. bottoms-up The Company has completed its initial evaluation of the impact of ASU 2014-09 non-executive 2014-09 2014-09, No. 2014-09 In February 2016, the FASB issued guidance on accounting for leases that generally requires all leases to be recognized on the consolidated balance sheet. The provisions of the guidance are effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. The Company plans to adopt this guidance in fiscal year beginning May 1, 2019. The provisions of the guidance are to be applied using a modified retrospective approach. The Company is still evaluating the effect this guidance will have on the consolidated financial statements. Based on our initial assessment, the Company expects that upon adoption it will report an increase in assets and liabilities on our consolidated balance sheet as a result of recognizing right-of-use In August 2016, the FASB issued guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. The new guidance provides clarification on specific cash flow issues regarding presentation and classification in the statement of cash flows with the objective of reducing the existing diversity in practice. The amendments in this update are effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Company plans to adopt this guidance in its fiscal year beginning May 1, 2018. The provisions of the guidance are to be applied using a retrospective transition method. The adoption of this guidance is not anticipated to have a material impact on the consolidated financial statements. In January 2017, the FASB issued guidance that clarifies the definition of a business. The new guidance assists a company when evaluating whether transactions should be accounted for as acquisitions (disposals) of assets or businesses. The provisions of the guidance require that if the fair value of the gross assets acquired (or disposed of) is substantially concentrated in a single identifiable asset or a group of similar identifiable assets, then it is not a business. The provisions of the guidance are effective for annual years beginning after December 15, 2017, including interim periods, with early adoption permitted. The Company plans to adopt this guidance in its fiscal year beginning May 1, 2018. The provisions of the guidance are to be applied prospectively. The adoption of this guidance is not anticipated to have a material impact on the consolidated financial statements. In January 2017, the FASB issued guidance simplifying the test for goodwill impairment. The new guidance simplifies the test for goodwill impairment by removing Step 2 from the goodwill impairment test. Companies will now perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value not to exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments of this standard are effective for goodwill impairment tests in fiscal years beginning after December 15, 2019, with early adoption permitted for goodwill impairment tests performed after January 1, 2017. The Company is evaluating the adoption timeline and the effects that the standard will have on the consolidated financial statements. In March 2017, the FASB issued guidance that changes the presentation of net periodic pension cost and net periodic postretirement benefit cost. The new guidance will change the presentation of net periodic benefit cost related to employer sponsored defined benefit plans and other postretirement benefits. Service cost will be included within the same income statement line item as other compensation costs arising from services rendered during the period, while other components of net periodic benefit pension cost will be presented separately outside of operating income. Additionally, only service costs may be capitalized in assets. The amendments of this standard are effective for fiscal years beginning after December 15, 2017, including interim periods within those years. The Company will adopt this guidance in its fiscal year beginning May 1, 2018. The adoption of this standard is not anticipated to have a material impact on the consolidated financial statements. In May 2017, the FASB issued guidance clarifying the scope of modification accounting for stock compensation. The new standard provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. This pronouncement is effective for annual reporting periods beginning after December 15, 2017, but early adoption is permitted. The Company will adopt this guidance in its fiscal year beginning May 1, 2018. The Company is currently evaluating the impact of adopting this guidance. In August 2017, the FASB issued guidance amending and simplifying accounting for hedging activities. The new guidance will refine and expand strategies that qualify for hedge accounting and simplify the application of hedge accounting in certain situation. The amendments of this standard are effective for fiscal years beginning after December 15, 2018. The Company will adopt this guidance in its fiscal year beginning May 1, 2019. The Company is currently evaluating the impact of adopting this guidance.

The Third A&R 2008 Plan provides for the grant of awards to eligible participants, designated as either nonqualified or incentive stock options, restricted stock and restricted stock units, any of which may be performance-based or market-based, and incentive bonuses, which may be paid in cash or stock or a combination thereof. Under the Third A&R 2008 Plan, the ability to issue full-value awards is limited by requiring full-value stock awards to count 2.3 times as much as stock options. Restricted Stock The Company grants time-based restricted stock awards to executive officers and other senior employees generally vesting over a four-year period. In addition, certain key management members typically receive time-based restricted stock awards upon commencement of employment and may receive them annually in conjunction with the Company’s performance review. Time-based restricted stock awards are granted at a price equal to fair value, which is determined based on the closing price of the Company’s common stock on the grant date. The Company recognizes compensation expense for time-based restricted stock awards on a straight-line basis over the vesting period. The Company also grants market-based and performance-based restricted stock units to executive officers and other senior employees. The market-based units vest after three years depending upon the Company’s total stockholder return over the three-year performance period relative to other companies in its selected peer group. The fair value of these market-based restricted stock units is determined by using extensive market data that is based on historical Company and peer group information. The Company recognizes compensation expense for market-based restricted stock units on a straight-line basis over the vesting period. Performance-based restricted stock units vest after three years depending upon the Company meeting certain objectives that are set at the time the restricted stock unit is issued. Performance-based restricted stock units are granted at a price equal to the fair value, which is determined based on the closing price of the Company’s common stock on the grant date. At the end of each reporting period, the Company estimates the number of restricted stock units expected to vest, based on the probability that certain performance objectives will be met, exceeded, or fall below target levels, and the Company takes into account these estimates when calculating the expense for the period. Restricted stock activity during the six months ended October 31, 2017 is summarized below: Shares Weighted- (in thousands, except per share data) Non-vested, 1,581 $ 29.74 Granted 623 $ 37.46 Vested (409 ) $ 25.91 Forfeited/expired (62 ) $ 33.19 Non-vested, 1,733 $ 33.30 As of October 31, 2017, there were 0.7 million shares and 0.2 million shares outstanding relating to market-based and performance-based restricted stock units, respectively, with total unrecognized compensation totaling $11.4 million and $5.6 million, respectively.

Employees may not purchase more than $25,000 in stock during any calendar year. The maximum number of shares that may be issued under the ESPP is 3.0 million shares. During the three months ended October 31, 2017 and 2016, no shares were purchased under the ESPP.

The Company has designated the swap as a cash flow hedge. The notional amount will be amortized so that the amount is always half of the principal balance of the debt outstanding. As of October 31, 2017, the notional amount was $124.6 million. The interest rate swap agreement matures on June 15, 2021 and locks the interest rates on half the debt outstanding at 1.919%, exclusive of the credit spread on the debt. The fair value of the derivative designated as a cash flow hedge instrument is as follows: October 31, 2017 April 30, 2017 (in thousands) Derivative liability: Interest rate swap contract $ 303 $ 947 During the three and six months ended October 31, 2017, the Company recognized the following gains and losses on the interest rate swap: Three Months Six Months October 31, 2017 (in thousands) Gains recognized in other comprehensive income (net of tax effects of $205 and $56, respectively) $ 322 $ 88 Losses reclassified from accumulated other comprehensive income into interest expense, net $ 220 $ 500 As the critical terms of the hedging instrument and the hedged forecasted transaction are the same, the Company has concluded that the changes in the fair value or cash flows attributable to the risk being hedged are expected to completely offset at inception and on an ongoing basis. We estimate that $0.5 million of derivative losses included in accumulated other comprehensive income as of October 31, 2017 will be reclassified into other expense within the following 12 months. The cash flows related to the interest rate swap contract are included in net cash provided by operating activities. Non-Designated The fair value of derivatives not designated as hedge instruments are as follows: October 31, 2017 April 30, 2017 (in thousands) Derivative assets: Total gross amount of foreign currency forward contracts $ 1,528 $ — Gross derivatives offset on the balance sheet (1) (474 ) — Net amounts presented on the balance sheet $ 1,054 $ — Derivative liabilities: Total gross amount of foreign currency forward contracts $ 1,075 $ 846 Gross derivatives offset on the balance sheet (1) (474 ) (129 ) Net amounts presented on the balance sheet $ 601 $ 717 (1) These amounts represent the impact of netting derivative assets and derivative liabilities when a legally enforceable master netting agreement exists and fair value of adjustments related to our counterparty credit risk. As of October 31, 2017, the total notional amounts of the forward contracts purchased and sold were $22.4 million and $63.2 million, respectively. As of April 30, 2017, the total notional amounts of the forward contracts purchased and sold were $19.4 million and $70.0 million, respectively. During the three months ended October 31, 2017, the Company incurred gains of $0.3 million related to forward contracts which is recorded in general and administrative expenses in the accompanying consolidated statements of income.

Deferred Compensation and Retirement Plans	7. Deferred Compensation and Retirement Plans The Company has several deferred compensation and retirement plans for eligible consultants and vice presidents that provide defined benefits to participants based on the deferral of current compensation or contributions made by the Company subject to vesting and retirement or termination provisions. Among these plans is a defined benefit pension plan for certain Hay Group employees in the United States. The assets of this plan are held separately from the assets of the sponsors in self-administered funds. The plan is funded consistent with local statutory requirements and the Company expects to contribute $0.2 million to this plan during fiscal 2018. All other defined benefit obligations from other plans are unfunded. The components of net periodic benefit costs are as follows: Three Months Ended October 31, Six Months Ended October 31, 2017 2016 2017 2016 (in thousands) Service cost $ 3,165 $ 1,579 $ 5,291 $ 2,188 Interest cost 959 1,061 1,918 2,123 Amortization of actuarial loss 577 763 1,154 1,526 Expected return on plan assets (1) (398 ) (390 ) (797 ) (780 ) Net periodic benefit costs $ 4,303 $ 3,013 $ 7,566 $ 5,057 (1) The expected long-term rate of return on plan assets is 6.50% for October 31, 2017 and 2016. The Company purchased COLI contracts insuring the lives of certain employees eligible to participate in the deferred compensation and pension plans as a means of funding benefits under such plans. The gross CSV of these contracts of $182.5 million and $180.3 million is offset by outstanding policy loans of $66.8 million and $67.2 million in the accompanying consolidated balance sheets as of October 31, 2017 and April 30, 2017, respectively. The CSV value of the underlying COLI investments increased by $1.7 million and $4.2 million during the three and six months ended October 31, 2017, respectively, and is recorded as a decrease in compensation and benefits expense in the accompanying consolidated statements of income. The CSV value of the underlying COLI investments increased by $0.7 million and $3.2 million during the three and six months ended October 31, 2016, respectively, and is recorded as a decrease in compensation and benefits expense in the accompanying consolidated statements of income. The Company’s ECAP is intended to provide certain employees an opportunity to defer salary and/or bonus on a pre-tax The ECAP is accounted for whereby the changes in the fair value of the vested amounts owed to the participants are adjusted with a corresponding charge (or credit) to compensation and benefits costs. During the three and six months ended October 31, 2017, deferred compensation liability increased; therefore, the Company recognized an increase in compensation expense of $3.5 million and $7.2 million, respectively. Offsetting the increase in compensation and benefits expense was an increase in the fair value of marketable securities classified as trading (held in trust to satisfy obligations under the ECAP) of $3.4 million and $6.8 million during the three and six months ended October 31, 2017, respectively, recorded in other income (loss), net on the consolidated statements of income.

During the six months ended October 31, 2016, deferred compensation liability increased; therefore, the Company recognized $2.6 million in compensation expense. Offsetting the increase in compensation and benefits expense was an increase in the fair value of marketable securities classified as trading (held in trust to satisfy obligations under certain deferred compensation liabilities) of $3.2 million during the six months ended October 31, 2016, recorded in other income (loss), net on the consolidated statements of income (see Note 6 — Financial Instruments

Long-Term Debt

Long-Term Debt	6 Months Ended

Long-Term Debt	10. Long-Term Debt On June 15, 2016, the Company entered into a senior secured $400 million Credit Agreement (the “Credit Agreement”) with a syndicate of banks and Wells Fargo Bank, National Association as administrative agent (to provide for enhanced financial flexibility and in recognition of the accelerated pace of the Hay Group integration). The Credit Agreement provides for, among other things: (a) a senior secured term loan facility in an aggregate principal amount of $275 million (the “Term Facility”), (b) a senior secured revolving credit facility (the “Revolver” and together with the Term Facility, the “Credit Facilities”) in an aggregate principal amount of $125 million, (c) annual term loan amortization of 7.5%, 7.5%, 10.0%, 10.0% and 10.0%, with the remaining principal due at maturity, (d) certain customary affirmative and negative covenants, including a maximum consolidated total leverage ratio (as defined below) and a minimum interest coverage ratio and (e) an expanded definition of permitted add-backs pay-off At the Company’s option, loans issued under the Credit Agreement will bear interest at either 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 LIBOR plus 1.25% per annum to LIBOR plus 2.00% per annum, in the case of LIBOR borrowings (or between the alternate base rate plus 0.25% per annum and the alternate base rate plus 1.00% 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 lenders a quarterly fee ranging from 0.20% to 0.35% per annum on the average daily unused amount of the Term Facility, based upon the Company’s consolidated leverage ratio at such time and fees relating to the issuance of letters of credit. During the three and six months ended October 31, 2017, the average rate on the Term Facility was 2.49% and 2.41%, respectively. During the three and six months ended October 31, 2016, the average rate on the Term Facility was 2.44% and 2.43%, respectively. Both the Revolver and the Term Facility mature on June 15, 2021 and may be prepaid and terminated early by the Company at any time without premium or penalty (subject to customary LIBOR breakage fees). The Term Facility is payable in quarterly installments with principal payments totalling $10.3 million made during the six months ended October 31, 2017. As of October 31, 2017, $249.2 million was outstanding under the Term Facility compared to $259.5 million as of April 30, 2017. The current and long-term portion of unamortized debt issuance costs associated with the long-term debt, was $3.1 million and $3.5 million as of October 31, 2017 and April 30, 2017, respectively. The fair value of the Company’s Term Facility is based on borrowing rates currently required of loans with similar terms, maturity and credit risk. The carrying amount of the Term Facility approximates fair value because the base interest rate charged varies with market conditions and the credit spread is commensurate with current market spreads for issuers of similar risk. The fair value of the Term Facility is classified as a Level 2 liability in the fair value hierarchy. As of October 31, 2017, the Company was in compliance with its debt covenants. As of October 31, 2017 and April 30, 2017, the Company had no borrowings under the Revolver. The Company had $3.0 million of standby letters of credits issued under its long-term debt arrangements as of October 31, 2017 and April 30, 2017, respectively. The Company had a total of $8.2 million and $8.1 million of standby letters of credits with other financial institutions as of October 31, 2017 and April 30, 2017, respectively. The standby letters of credits were generally issued as a result of entering into office premise leases.

Organization and Summary of S18

Organization and Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Oct. 31, 2017
Basis of Consolidation and Presentation	Basis of Consolidation and Presentation The accompanying financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K Investments in affiliated companies, which are 50% or less owned and where the Company exercises significant influence over operations, are accounted for using the equity method. The Company has control of a Mexico subsidiary and consolidates the operations of this subsidiary. Noncontrolling interest, which represents the Company’s 51% noncontrolling interest in the Mexico subsidiary, is reflected on the Company’s consolidated financial statements. The Company considers events or transactions that occur after the balance sheet date but before the consolidated financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosures.
Use of Estimates and Uncertainties	Use of Estimates and Uncertainties The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates and changes in estimates are reported in current operations as new information is learned or upon the amounts becoming fixed and determinable. The most significant areas that require management judgment are revenue recognition, restructuring, deferred compensation, annual performance related bonuses, evaluation of the carrying value of receivables, goodwill and other intangible assets, fair value of contingent consideration, share-based payments and the recoverability of deferred income taxes.
Revenue Recognition	Revenue Recognition Substantially all fee revenue is derived from fees for professional services related to executive search performed on a retained basis, recruitment for non-executive non-executive one-third non-executive non-executive Depending on the timing of billings and services rendered, the Company accrues or defers revenue as appropriate. Hay Group revenue is also derived from the sale of product services, which includes revenue from licenses and from the sale of products. Revenue from licenses is recognized using a straight-line method over the term of the contract (generally 12 months). Under fixed term licenses, the Company is obligated to provide the licensee with access to any updates to the underlying intellectual property that are made by the Company during the term of the license. Once the term of the agreement expires, the client’s right to access or use the intellectual property expires and the Company has no further obligations to the client under the license agreement. Revenue from perpetual licenses is recognized when the license is sold since the Company’s only obligation is to provide the client access to the intellectual property but is not obligated to provide maintenance, support, updates or upgrades. Products sold by the Company mainly consist of books and automated services covering a variety of topics including performance management, team effectiveness, and coaching and development. The Company recognizes revenue for its products when the product has been sold or shipped in the case of books. As of October 31, 2017 and April 30, 2017, the Company included deferred revenue of $100.2 million and $95.8 million, respectively, in other accrued liabilities.
Reimbursements	Reimbursements The Company incurs certain out-of-pocket
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts An allowance is established for doubtful accounts by taking a charge to general and administrative expenses. The amount of the allowance is based on historical loss experience, assessment of the collectability of specific accounts, as well as expectations of future collections based upon trends and the type of work for which services are rendered. After the Company exhausts all collection efforts, the amount of the allowance is reduced for balances identified as uncollectible. .
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. As of October 31, 2017 and April 30, 2017, the Company’s investments in cash equivalents consist of money market funds for which market prices are readily available.
Marketable Securities	Marketable Securities The Company currently has investments in mutual funds that are classified as trading securities based upon management’s intent and ability to hold, sell or trade such securities. The classification of the investments in mutual funds is assessed upon purchase and reassessed at each reporting period. The investments in mutual funds (for which market prices are readily available) are held in trust to satisfy obligations under the Company’s deferred compensation plans. Such investments are based upon the employees’ investment elections in their deemed accounts in the Executive Capital Accumulation Plan and similar plans in Asia Pacific and Canada (“ECAP”) from a pre-determined ex-dividend
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is the price the Company would receive to sell an asset or transfer a liability (exit price) in an orderly transaction between market participants. For those assets and liabilities recorded or disclosed at fair value, the Company determines the fair value based upon the quoted market price, if available. If a quoted market price is not available for identical assets, the fair value is based upon the quoted market price of similar assets. The fair values are assigned a level within the fair value hierarchy as defined below: ◾ Level 1: ◾ Level 2: ◾ Level 3: As of October 31, 2017 and April 30, 2017, the Company held certain assets that are required to be measured at fair value on a recurring basis. These included cash, cash equivalents, accounts receivable, marketable securities, foreign currency forward contracts and interest rate swap. The carrying amount of cash, cash equivalents and accounts receivable approximates fair value due to the short maturity of these instruments. The fair values of marketable securities classified as trading are obtained from quoted market prices and the fair values of foreign currency forward contracts or the interest rate swap are obtained from a third party, which are based on quoted prices or market prices for similar assets and financial instruments.
Derivative Financial Instruments	Derivative Financial Instruments The Company is exposed to interest rate risk due to the outstanding senior secured credit agreement entered on June 15, 2016. The Company has entered into an interest rate swap agreement to effectively convert its variable debt to a fixed-rate basis. The principal objective of these contracts is to eliminate or reduce the variability of the cash flows in interest payments associated with the Company’s long-term debt, thus reducing the impact of interest rate changes on future interest payment cash flows. The Company has determined that the interest rate swap qualifies as a cash flow hedge in accordance with Accounting Standards Codification 815, Derivatives and Hedging
Foreign Currency Forward Contracts Not Designated as Hedges	Foreign Currency Forward Contracts Not Designated as Hedges The Company has established a program that primarily utilizes foreign currency forward contracts to offset the risks associated with the effects of certain foreign currency exposures. These foreign currency forward contracts are neither used for trading purposes nor are they designated as hedging instruments pursuant to Accounting Standards Codification 815, Derivatives and Hedging
Business Acquisitions	Business Acquisitions Business acquisitions are accounted for under the acquisition method. The acquisition method requires the reporting entity to identify the acquirer, determine the acquisition date, recognize and measure the identifiable assets acquired, the liabilities assumed and any noncontrolling interest in the acquired entity and recognize and measure goodwill or a gain from the purchase. The acquiree’s results are included in the Company’s consolidated financial statements from the date of acquisition. Assets acquired and liabilities assumed are recorded at their fair values and the excess of the purchase price over the amounts assigned is recorded as goodwill, or if the fair value of the assets acquired exceeds the purchase price consideration, a bargain purchase gain is recorded. Adjustments to fair value assessments are generally recorded to goodwill over the measurement period (not longer than twelve months). The acquisition method also requires that acquisition-related transaction and post-acquisition restructuring costs be charged to expense as committed and requires the Company to recognize and measure certain assets and liabilities including those arising from contingencies and contingent consideration in a business combination.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of the purchase price over the fair value of assets acquired. The goodwill impairment test compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, goodwill of the reporting unit would be considered impaired. To measure the amount of the impairment loss, the implied fair value of a reporting unit’s goodwill is compared to the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. If the carrying amount of a reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. For each of these tests, the fair value of each of the Company’s reporting units is determined using a combination of valuation techniques, including a discounted cash flow methodology. To corroborate the discounted cash flow analysis performed at each reporting unit, a market approach is utilized using observable market data such as comparable companies in similar lines of business that are publicly traded or which are part of a public or private transaction (to the extent available). Results of the annual impairment test performed as of January 31, 2017, indicated that the fair value of each reporting unit exceeded its carrying amount and no reporting units were at risk of failing the impairment test. As a result, no impairment charge was recognized. There was also no indication of potential impairment as of October 31, 2017 and April 30, 2017 that would have required further testing. Intangible assets primarily consist of customer lists, non-compete
Compensation and Benefits Expense	Compensation and Benefits Expense Compensation and benefits expense in the accompanying consolidated statements of income consist of compensation and benefits paid to consultants (employees who originate business), executive officers and administrative and support personnel. The most significant portions of this expense are salaries and the amounts paid under the annual performance related bonus plan to employees. The portion of the expense applicable to salaries is comprised of amounts earned by employees during a reporting period. The portion of the expenses applicable to annual performance related bonuses refers to the Company’s annual employee performance related bonus with respect to a fiscal year, the amount of which is communicated and paid to each eligible employee following the completion of the fiscal year. Each quarter, management makes its best estimate of its annual performance related bonuses, which requires management to, among other things, project annual consultant productivity (as measured by engagement fees billed and collected by executive search consultants and revenue and other performance/profitability metrics for Hay Group and Futurestep consultants), the level of engagements referred by a consultant in one line of business to a different line of business, Company performance including profitability, competitive forces and future economic conditions and their impact on the Company’s results. At the end of each fiscal year, annual performance related bonuses take into account final individual consultant productivity (including referred work), Company/line of business results including profitability, the achievement of strategic objectives, the results of individual performance appraisals and the current economic landscape. Accordingly, each quarter the Company reevaluates the assumptions used to estimate annual performance related bonus liability and adjusts the carrying amount of the liability recorded on the consolidated balance sheet and reports any changes in the estimate in current operations. Because annual performance-based bonuses are communicated and paid only after the Company reports its full fiscal year results, actual performance-based bonus payments may differ from the prior year’s estimate. Such changes in the bonus estimate historically have been immaterial and are recorded in current operations in the period in which they are determined. The performance related bonus expense was $98.5 million and $95.1 million during the six months ended October 31, 2017 and 2016, respectively, included in compensation and benefits expense in the consolidated statements of income. During the three months ended October 31, 2017 and 2016, the performance related bonus expense was $56.9 million and $52.7 million, respectively. Other expenses included in compensation and benefits expense are due to changes in deferred compensation and pension plan liabilities, changes in cash surrender value (“CSV”) of company owned life insurance (“COLI”) contracts, amortization of stock compensation awards, payroll taxes and employee insurance benefits. Investments and other assets include long-term retention awards that are generally amortized over four to five years.
Restructuring Charges, Net	Restructuring Charges, Net The Company accounts for its restructuring charges as a liability when the obligations are incurred and records such charges at fair value. Such charges included one-time
Stock-Based Compensation	Stock-Based Compensation The Company has employee compensation plans under which various types of stock-based instruments are granted. These instruments principally include restricted stock units, restricted stock, stock options and an Employee Stock Purchase Plan (“ESPP”). The Company recognizes compensation expense related to restricted stock units, restricted stock and the estimated fair value of stock options and stock purchases under the ESPP on a straight-line basis over the service period for the entire award.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In March 2016, the Financial Accounting Standards Board (the “FASB”) issued guidance on accounting for certain aspects of share-based payments to employees. The new guidance requires excess tax benefits and tax deficiencies to be recorded in the income statement when the awards vest or are settled. Furthermore, cash flows related to excess tax benefits will no longer be separately classified as a financing activity apart from other income tax cash flows. The guidance also allows companies to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting, clarifying that all cash payments made on an employee’s behalf for withheld shares should be presented as a financing activity in the consolidated statements of cash flows and provides an accounting policy election to account for forfeitures as they occur. The provisions of the guidance are effective for fiscal years beginning after December 15, 2016 and were adopted by the Company effective May 1, 2017. The primary impact of the adoption was the recognition of excess tax benefits in our provision for income taxes in the current year compared to recording it previously as a component of equity. Additional amendments to the accounting for income taxes and minimum statutory withholding tax requirements had no impact to retained earnings, where the cumulative effect of these changes are required to be recorded. The Company elected to apply the presentation for cash flows related to excess tax benefits retrospectively for all periods presented which resulted in minimal impact to cash used in operations and cash provided by financing activities for the six months ended October 31, 2016. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact on any of the periods presented on our consolidated cash flows statements since such cash flows have historically been presented as a financing activity. The Company elected to account for forfeitures as they occur, rather than estimating the expected forfeitures over the vesting period. This election did not have an impact on the Company’s financial statements.
Recently Proposed Accounting Standards	Recently Proposed Accounting Standards In May 2014, the FASB issued ASU 2014-09, 2014-09: The new guidance is effective for fiscal years and interim periods within those annual years beginning after December 15, 2017. The Company will adopt this guidance in its fiscal year beginning May 1, 2018 and expects to apply the modified retrospective method in adopting ASU 2014-09. bottoms-up The Company has completed its initial evaluation of the impact of ASU 2014-09 non-executive 2014-09 2014-09, No. 2014-09 In February 2016, the FASB issued guidance on accounting for leases that generally requires all leases to be recognized on the consolidated balance sheet. The provisions of the guidance are effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. The Company plans to adopt this guidance in fiscal year beginning May 1, 2019. The provisions of the guidance are to be applied using a modified retrospective approach. The Company is still evaluating the effect this guidance will have on the consolidated financial statements. Based on our initial assessment, the Company expects that upon adoption it will report an increase in assets and liabilities on our consolidated balance sheet as a result of recognizing right-of-use In August 2016, the FASB issued guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. The new guidance provides clarification on specific cash flow issues regarding presentation and classification in the statement of cash flows with the objective of reducing the existing diversity in practice. The amendments in this update are effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Company plans to adopt this guidance in its fiscal year beginning May 1, 2018. The provisions of the guidance are to be applied using a retrospective transition method. The adoption of this guidance is not anticipated to have a material impact on the consolidated financial statements. In January 2017, the FASB issued guidance that clarifies the definition of a business. The new guidance assists a company when evaluating whether transactions should be accounted for as acquisitions (disposals) of assets or businesses. The provisions of the guidance require that if the fair value of the gross assets acquired (or disposed of) is substantially concentrated in a single identifiable asset or a group of similar identifiable assets, then it is not a business. The provisions of the guidance are effective for annual years beginning after December 15, 2017, including interim periods, with early adoption permitted. The Company plans to adopt this guidance in its fiscal year beginning May 1, 2018. The provisions of the guidance are to be applied prospectively. The adoption of this guidance is not anticipated to have a material impact on the consolidated financial statements. In January 2017, the FASB issued guidance simplifying the test for goodwill impairment. The new guidance simplifies the test for goodwill impairment by removing Step 2 from the goodwill impairment test. Companies will now perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value not to exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments of this standard are effective for goodwill impairment tests in fiscal years beginning after December 15, 2019, with early adoption permitted for goodwill impairment tests performed after January 1, 2017. The Company is evaluating the adoption timeline and the effects that the standard will have on the consolidated financial statements. In March 2017, the FASB issued guidance that changes the presentation of net periodic pension cost and net periodic postretirement benefit cost. The new guidance will change the presentation of net periodic benefit cost related to employer sponsored defined benefit plans and other postretirement benefits. Service cost will be included within the same income statement line item as other compensation costs arising from services rendered during the period, while other components of net periodic benefit pension cost will be presented separately outside of operating income. Additionally, only service costs may be capitalized in assets. The amendments of this standard are effective for fiscal years beginning after December 15, 2017, including interim periods within those years. The Company will adopt this guidance in its fiscal year beginning May 1, 2018. The adoption of this standard is not anticipated to have a material impact on the consolidated financial statements. In May 2017, the FASB issued guidance clarifying the scope of modification accounting for stock compensation. The new standard provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. This pronouncement is effective for annual reporting periods beginning after December 15, 2017, but early adoption is permitted. The Company will adopt this guidance in its fiscal year beginning May 1, 2018. The Company is currently evaluating the impact of adopting this guidance. In August 2017, the FASB issued guidance amending and simplifying accounting for hedging activities. The new guidance will refine and expand strategies that qualify for hedge accounting and simplify the application of hedge accounting in certain situation. The amendments of this standard are effective for fiscal years beginning after December 15, 2018. The Company will adopt this guidance in its fiscal year beginning May 1, 2019. The Company is currently evaluating the impact of adopting this guidance.
