Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	1. Organization and Summary of Significant Accounting Policies Nature of Business (i) 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 for the year ended April 30, 2018 for the Company and its wholly and majority owned/controlled domestic and international subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The preparation of the consolidated financial statements conform with United States (“U.S.”) generally accepted accounting principles (“GAAP”) and prevailing practice within the industry. The consolidated financial statements include all adjustments, consisting of normal recurring accruals and any other adjustments that management considers necessary for a fair presentation of the results for these periods. The results of operations for the interim period are not necessarily indicative of the results for the entire fiscal year. 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 or determinable. The most significant areas that require management’s judgment are revenue recognition, deferred compensation, annual performance related bonuses, evaluation of the carrying value of receivables, goodwill and other intangible assets, share-based payments and the recoverability of deferred income taxes. Revenue Recognition either Revenue is recognized when control of the goods and services are transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods and services. Revenue contracts with customers are evaluated based on the five-step model outlined in Accounting Standard Codification 606 (“ASC 606”): 1) identify the contract with a customer; 2) identify the performance obligation(s) in the contract; 3) determine the transaction price; 4) allocate the transaction price to the separate performance obligation(s); and 5) recognize revenue when (or as) each performance obligation is satisfied. Fee revenue from executive and non-executive professional search activities is generally one-third of the estimated first year compensation of the placed candidate plus a percentage of the fee to cover RPO fee Consulting fee revenue, primarily generated from Advisory, is recognized as services are rendered, measured by total hours incurred to the total estimated hours at completion. It is possible that updated estimates for consulting engagements may vary from initial estimates with such updates being recognized in the period of determination. Depending on the timing of billings and services rendered, the Company accrues or defers revenue as appropriate. Product revenue is generated from a range of online tools designed to support human resource processes for pay, talent and engagement, assessments, as well as licenses to proprietary intellectual property (“IP”) and tangible/digital products. IP Functional IP licenses grant customers the right to use IP content via delivery of a flat file. Because the IP content license has significant standalone functionality, revenue is recognized upon delivery and when an enforceable right to payment exists . Online assessments are delivered in the form of online questionnaires. A bundle of assessments represents one performance obligation, and revenue is recognized as assessment services are delivered and the Company has a legally enforceable right to payment. Reimbursements The Company incurs certain out-of-pocket expenses that are reimbursed by its clients, which are accounted for as revenue in its consolidated statements of income. 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, 2018 and April 30, 2018, 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 (for which market prices are readily available) that 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 set of securities and the Company invests in marketable securities to mirror these elections. These investments are recorded at fair value with the change in value in the period being reflected in the consolidated statements of income and are classified as marketable securities in the accompanying consolidated balance sheets. The investments that the Company may sell within the next twelve months are carried as current assets. Realized gains (losses) on marketable securities are determined by specific identification. Interest is recognized on an accrual basis; dividends are recorded as earned on the ex-dividend date. Interest, dividend income and the changes in fair value in marketable securities are recorded in the accompanying consolidated statements of income in other (loss) income, net. 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: Observable inputs such as quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. ▪ Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. ▪ Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions. As of October 31, 2018 and April 30, 2018, 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 an interest rate swap. The carrying amount of cash, cash equivalents and accounts receivable approximates fair value due to the short-term maturity of these instruments. The fair values of marketable securities are obtained from quoted market prices, and the fair values of foreign currency forward contracts and 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 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 primarily originating from intercompany balances due to cross border work performed in the ordinary course of business. 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, 2018, 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, 2018 and April 30, 2018 that would have required further testing. Intangible assets primarily consist of customer lists, non-compete agreements, proprietary databases and intellectual property. Intangible assets are recorded at their estimated fair value at the date of acquisition and are amortized in a pattern in which the asset is consumed if that pattern can be reliably determined, or using the straight-line method over their estimated useful lives which range from one to 24 years. For intangible assets subject to amortization, an impairment loss is recognized if the carrying amount of the intangible assets is not recoverable and exceeds fair value. The carrying amount of the intangible assets is considered not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from use of the asset. Intangible assets with indefinite lives are not amortized, but are reviewed annually for impairment or more frequently whenever events or changes in circumstances indicate that the fair value of the asset may be less than its carrying amount. As of October 31, 2018 and April 30, 2018, there were no further indicators of impairment with respect to the Company’s intangible assets, with the exception of the intangible asset impairment charge discussed below. On June 12, 2018, the Company’s Board of Directors voted to approve a rebranding plan with the Company going to market under a single, master brand architecture, solely as Korn Ferry and sunsetting of all the Company’s sub-brands, including Futurestep, Hay Group and Lominger, among others. This integrated go-to-market approach was a key driver in our fee revenue growth in fiscal 2018, which led to the decision to further integrate our go-to-market activities under one master brand – Korn Ferry. As a result, the Company discontinued the use of all sub-brands. Two of the Company’s sub-brands, Hay Group and Lominger came to Korn Ferry through acquisitions. In connection with the accounting for these acquisitions, $106.6 million of the purchase price was allocated to indefinite lived tradename intangible assets. As a result of the decision to discontinue their use, the Company took a non-cash intangible asset impairment charge of $106.6 million, during the six months ended October 31, 2018 recorded in general and administrative expenses. No impairment charge was recorded during the three months ended October 31, 2018. 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 Advisory and RPO and Professional Search 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 and 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 $142.9 million and $98.5 million during the six months ended October 31, 2018 and 2017, respectively, included in compensation and benefits expense in the consolidated statements of income. During the three months ended October 31, 2018 and 2017, the performance related bonus was $81.9 million and $56.9 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. Unearned compensation on the consolidated balance sheets includes 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 employee termination benefits and the cost to terminate an office lease including remaining lease payments. Changes in the estimates of the restructuring charges are recorded in the period the change is determined. 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 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 purchases under the ESPP on a straight-line basis over the service period for the entire award. Reclassifications Certain reclassifications have been made to the amounts in prior periods in order to conform to the current period’s presentation. Recently Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (“ FASB”) issued ASC 606, which superseded revenue recognition requirements regarding contracts with customers to transfer goods or services The Company recognized the cumulative effect of initially applying the new guidance as an adjustment to the opening balance of retained earnings. The comparative periods have not been restated and continue to be reported under the revenue accounting standards in effect for those periods. As a result of the adoption, the Company recorded an increase to retained earnings of $6.7 million, net of tax as of May 1, 2018 due to the cumulative impact of adopting ASC 606. The change in total assets was recorded to unbilled receivables which is included in receivables due from clients; the changes in total liabilities was recorded to income taxes payable, deferred tax liabilities and deferred revenue, which is included in other accrued liabilities. The following table summarizes the effect of changes made to our consolidated balance sheet at May 1, 2018: Adjustments April 30, 2018 due to ASC 606 May 1, 2018 (in thousands) Total assets $ 2,287,914 $ 3,496 $ 2,291,410 Total liabilities $ 1,068,299 $ (3,160 ) $ 1,065,139 Total stockholders’ equity $ 1,219,615 $ 6,656 $ 1,226,271 term licenses and revenue was recognized ratably over the contract term. 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 and were adopted by the Company effective May 1, 2018. The adoption of this guidance did not have an impact on the Company’s 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 to be applied prospectively. The provisions of the guidance are effective for annual years beginning after December 15, 2017 and were adopted by the Company effective May 1, 2018. The adoption of this guidance did not have an impact on the Company’s 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. This pronouncement is effective for annual reporting periods beginning after December 15, 2017 and was adopted by the Company effective May 1, 2018. The change to the c onsolidated statements of income Prior period amounts were revised, which resulted in a decrease in compensation expense and other income of $2.4 million and $0.4 million, respectively, and an increase in interest expense of $2.1 million in the six months ended October 31, 2017. During the three months ended October 31, 2017 prior period amounts were revised, which resulted in a decrease in compensation expense and other income of $1.2 million and $0.2 million, respectively, and an increase in interest expense of $1.0 million (see Note 6 — Deferred Compensation and Retirement Plans ). 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 and was adopted by the Company effective May 1, 2018. The adoption of this guidance did not have an impact on the Company’s consolidated financial statements. Any future impact of this guidance will be dependent on future modification including the number of awards modified. Cuts and Jobs Act of 2017 (the ” Tax Act”) from Recently Proposed Accounting Standards – Not Yet Adopted 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. On July 30, 2018, the FASB issued an amendment that allows entities to apply the provisions at the effective date without adjusting comparative periods. 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 assets and lease liabilities related to lease agreements. 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 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 situations. 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. In August 2018, the FASB issued guidance amending the disclosure requirements for fair value measurements. The amendment removes and modifies disclosures that are currently required and adds additional disclosures that are deemed relevant. The amendments of this standard are effective for fiscal years beginning after December 15, 2019. The Company will adopt this guidance in its fiscal year beginning May 1, 2020. In August 2018, the FASB issued guidance amending accounting for internal-use software. The new guidance will align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with developing or obtaining internal-use software. The amendments of this standard are effective for fiscal years ending after December 15, 2019 with early adoption permitted. The Company will adopt this guidance in its fiscal year beginning May 1, 2020. The Company is currently evaluating the impact of adopting this guidance. In August 2018, the FASB issued guidance amending and modifying the disclosure requirements for employers that sponsor defined benefit pension or other postretirement pension plans. The amendment removes disclosures to pension plans and other postretirement benefit plans that are no longer considered beneficial and adds disclosure requirements deemed relevant. The amendments of this standard are effective for fiscal years ending after December 15, 2020. The Company will adopt this guidance in its fiscal year beginning May 1, 2021. The Company is currently evaluating the impact of adopting this guidance.

Earnings Per Share [Abstract]
Basic and Diluted Earnings Per Share	2. Basic and Diluted Earnings Per Share Accounting Standards Codification 260, Earnings Per Share Basic earnings per common share was computed using the two-class method by dividing basic net earnings attributable to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per common share was computed using the two-class method by dividing diluted net earnings attributable to common stockholders by the weighted-average number of common shares outstanding plus dilutive common equivalent shares. Dilutive common equivalent shares include all in-the-money outstanding options or other contracts to issue common stock as if they were exercised or converted. Financial instruments that are not in the form of common stock, but when converted into common stock increase earnings per share are anti-dilutive and are not included in the computation of diluted earnings per share. During the three and six months ended October 31, 2018 and 2017, restricted stock awards of 0.6 million were outstanding, but not included in the computation of diluted earnings per share because they were anti-dilutive.

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 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 are 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, 2018 is summarized below: Shares Weighted- Average Grant Date Fair Value (in thousands, except per share data) Non-vested, April 30, 2018 1,730 $ 33.45 Granted 515 $ 52.81 Vested (572 ) $ 34.16 Forfeited/expired (25 ) $ 32.26 Non-vested, October 31, 2018 1,648 $ 42.22 As of October 31, 2018, there were 0.6 million shares and 0.2 million shares outstanding relating to market-based and performance-based restricted stock units, respectively, with total unrecognized compensation totaling $14.8 million and $0.4 million, respectively. As of October 31, 2018, there was $45.5 million of total unrecognized compensation cost related to all non-vested awards of restricted stock, which is expected to be recognized over a weighted-average period of 2.7 years. During the three and six months ended October 31, 2018, 2,708 shares and 202,503 shares of restricted stock totaling $0.1 million and $13.2 million, respectively, were repurchased by the Company, at the option of the employee, to pay for taxes related to vesting of restricted stock. During the three and six months ended October 31, 2017, 2,888 shares and 100,371 shares of restricted stock totaling $0.1 million and $3.4 million, respectively, were repurchased by the Company, at the option of employees, to pay for taxes related to vesting of restricted stock. Employee Stock Purchase Plan The Company has an ESPP that, in accordance with Section 423 of the Internal Revenue Code, allows eligible employees to authorize payroll deductions of up to 15% of their salary to purchase shares of the Company’s common stock at 85% of the fair market price of the common stock on the last day of the enrollment period. 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, 2018 and 2017, no shares were purchased under the ESPP. During the six months ended October 31, 2018 and 2017, employees purchased 75,106 shares at $52.64 per share and 116,285 shares at $29.35 Common Stock During the six months ended October 31, 2018 and 2017, the Company issued 6,720 shares and 41,075 shares of common stock, respectively, because of the exercise of stock options, with cash proceeds from the exercise of $0.2 million and $0.6 million, respectively. No stock options were exercised during the three months ended October 31, 2018 and 2017. During the three and six months ended October 31, 2018, the Company repurchased (on the open market) 456,274 shares of the Company’s common stock for $22.7 million. During the three and six months ended October 31, 2017, the Company repurchased (on the open market) 773,923 shares and 893,279 shares of the Company’s common stock for $25.3 million and $29.3 million, respectively.

Designated Derivatives - Interest Rate Swap Agreement In March 2017, the Company entered into an interest rate swap contract with a notional amount of $129.8 million, to hedge the variability to changes in cash flows attributable to interest rate risks caused by changes in interest rates related to its variable rate debt. 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, 2018, the notional amount was $113.4 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, 2018 April 30, 2018 (in thousands) Derivative asset: Interest rate swap contract $ 2,452 $ 2,076 During the three and six months ended October 31, 2018, the Company recognized the following gains and losses on the interest rate swap: Three Months Ended October 31, Six Months Ended October 31, 2018 2017 2018 2017 (in thousands) Gains (Losses) recognized in other comprehensive income (net of tax effects of $67, ($205), $120, and ($56), respectively) $ 193 $ (322 ) $ 342 $ (88 ) Gains (Losses) reclassified from accumulated other comprehensive income into interest expense, net $ 64 $ (220 ) $ 86 $ (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 $0.8 million of derivative gains included in accumulated other comprehensive income as of October 31, 2018 will be reclassified into interest expense, net within the following 12 months. The cash flows related to the interest rate swap contract are included in net cash provided by operating activities. Foreign Currency Forward Contracts Not Designated as Hedges The fair value of derivatives not designated as hedge instruments are as follows: October 31, 2018 April 30, 2018 (in thousands) Derivative assets: Foreign currency forward contracts $ 1,436 $ 1,778 Derivative liabilities: Foreign currency forward contracts $ 2,150 $ 1,025 As of October 31, 2018, the total notional amounts of the forward contracts purchased and sold were $36.4 million and $49.6 million, respectively. As of April 30, 2018, the total notional amounts of the forward contracts purchased and sold were $80.8 million and $78.5 million, respectively. The Company recognizes forward contracts as a net asset or net liability on the consolidated balance sheets as such contracts are covered by a master netting agreement. During the three months ended October 31, 2018 and six months ended October 31, 2018 and 2017, the Company incurred losses of $0.2 million, $0.1 million, and $2.3 million, respectively, related to forward contracts which is recorded in general and administrative expenses in the accompanying consolidated statements of income. These foreign currency losses offset foreign currency gains that result from transactions denominated in a currency other than the Company’s functional currency. During the three months ended October 31, 2017, the Company incurred a gain of $0.3 million related to forward contracts which is recorded in general and administrative expenses in the accompanying consolidated statements of income. These gains offset foreign currency losses that result from transactions denominated in a currency other than the Company’s functional currency. The cash flows related to foreign currency forward contracts are included in net cash used in operating activities.

Compensation And Retirement Disclosure [Abstract]
Deferred Compensation and Retirement Plans	6. 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 employees in the United States. The assets of this plan are held separately from the assets of the sponsors in self-administered funds. 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, 2018 2017 2018 2017 (in thousands) Service cost $ 4,532 $ 3,079 $ 8,178 $ 5,144 Interest cost 1,330 1,045 2,626 2,065 Amortization of actuarial loss 446 577 892 1,154 Expected return on plan assets (1) (392 ) (398 ) (784 ) (797 ) Net periodic service credit amortization (77 ) - (154 ) - Net periodic benefit costs (2) $ 5,839 $ 4,303 $ 10,758 $ 7,566 (1) The expected long-term rate of return on plan assets is 6.25% and 6.50% for October 31, 2018 and 2017, respectively. (2) The service cost, interest cost and the other components of net periodic benefit costs are included in compensation and benefits expense, interest expense, net and other (loss) income, net, respectively, on the consolidated statements of income. 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 setting aside funds to cover such plans. The gross CSV of these contracts of $219.2 and $186.8 million as of October 31, 2018 and April 30, 2018, respectively, The Company’s ECAP is intended to provide certain employees an opportunity to defer salary and/or bonus on a pre-tax basis. In addition, the Company, as part of its compensation philosophy, makes discretionary contributions into the ECAP and such contributions may be granted to key employees annually based on the employee’s performance. Certain key management may also receive Company ECAP contributions upon commencement of employment. The Company amortizes these contributions on a straight-line basis over the service period, generally a four- to five-year period. Participants have the ability to allocate their deferrals among a number of investment options and may receive their benefits at termination, retirement or “in service” either in a lump sum or in quarterly installments over one to 15 years. The ECAP amounts that are expected to be paid to employees over the next 12 months are classified as a current liability included in compensation and benefits payable on the accompanying balance sheet. 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, 2018, deferred compensation liability decreased; therefore, the Company recognized a decrease in compensation expense of $4.3 million and $0.2 million, respectively. Offsetting the decrease in compensation and benefits expense was a decrease in the fair value of marketable securities (held in trust to satisfy obligations under the ECAP) of $4.8 million and $0.8 million during the three and six months ended October 31, 2018, respectively, recorded in other (loss) income, net on the consolidated statements of income. 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 (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 (loss) income, net on the consolidated statements of income (see Note 5— Financial Instruments

Revenue From Contract With Customer [Abstract]
Fee Revenue	7. Fee Revenue Substantially all fee revenue is derived from fees for professional services related to executive and professional recruitment performed on a retained basis, recruitment process outsourcing, talent and organizational advisory services and the sale of products, standalone or as part of a solution. The Company adopted ASC 606 in its fiscal year beginning May 1, 2018 using the modified retrospective transition method applied to those contracts still outstanding and not completed as of May 1, 2018. Effect of the Adoption of ASC 606 The impact of adoption was immaterial. Contract Balances A contract asset (unbilled receivables) is recorded when the Company transfers control of products or services before there is an unconditional right to payment. A contract liability (deferred revenue) is recorded when cash is received in advance of performance of the obligation. Deferred revenue represents the future performance obligations to transfer control of products or services for which we have already received consideration. Deferred revenue is presented in other accrued liabilities on the consolidated balance sheet. The following table outlines our contract asset and liability balances as of October 31, 2018 and May 1, 2018: October 31, 2018 May 1, 2018 (in thousands) Contract assets (unbilled receivables) $ 78,403 $ 65,164 Contract liabilities (deferred revenue) $ 104,738 $ 114,695 During the six months ended October 31, 2018, we recognized revenue of $77.9 million that was included in the contract liabilities balance at the beginning of the period. Performance Obligations The Company has elected to apply the practical expedient to exclude the value of unsatisfied performance obligations for contracts with a duration of one year or less, which applies to all executive search and professional search fee revenue. As of October 31, 2018, the aggregate transaction price allocated to the performance obligations that are unsatisfied for contracts with an expected duration of greater than one year at inception was $486.1 million. Of the $486.1 million of remaining performance obligations, we expect to recognize approximately $160.6 million as fee revenue in fiscal 2019, $173.7 million in fiscal 2020, $84.2 million in fiscal 2021 and the remaining $67.6 million in fiscal 2022 and thereafter. However, this amount should not be considered an indication of the Company’s future revenue as contracts with an initial term of one year or less are not included. Further, our contract terms and conditions allow for clients to increase or decrease the scope of services and such changes do not become a performance obligation until the company has an enforceable right to payment. Disaggregation of revenue The Company disaggregates revenue by line of business and further by region for Executive Search. This information is presented in Note 9— Business Segments The following table provides further disaggregation of fee revenue by industry: Three Months Ended October 31, 2018 2017 Dollars % Dollars % (dollars in thousands) Industrial $ 144,199 29.1 % $ 132,648 29.9 % Financial Services 92,134 18.6 83,467 18.8 Life Sciences/ Healthcare 82,829 16.7 71,954 16.2 Consumer Goods 78,635 15.9 70,263 15.9 Technology 61,556 12.4 56,298 12.7 Education/Non-Profit 32,011 6.5 25,842 5.8 General 3,841 0.8 2,546 0.7 Fee Revenue $ 495,205 100.0 % $ 443,018 100.0 % Six Months Ended October 31, 2018 2017 Dollars % Dollars % (dollars in thousands) Industrial $ 279,963 29.1 % $ 254,095 30.1 % Financial Services 172,327 17.9 150,727 17.9 Life Sciences/ Healthcare 161,997 16.9 138,534 16.4 Consumer Goods 150,429 15.7 132,094 15.6 Technology 123,405 12.8 108,070 12.8 Education/Non-Profit 64,947 6.8 54,519 6.5 General 7,705 0.8 6,233 0.7 Fee Revenue $ 960,773 100.0 % $ 844,272 100.0 %

Income Taxes	8. Income Taxes The provision for income tax was an expense of $14.8 million in the three months ended October 31, 2018 and a benefit of $1.3 million in the six months ended October 31, 2018. This reflects a 23.9% (expense) and a 17.4% (benefit) effective tax rate compared to the U.S. federal statutory rate of 21.0%. This difference from the statutory rate is primarily due to the tradename impairment charge and the excess tax benefit on vested stock-based awards, both of which were recorded as discrete during the three months ended July 31, 2018. The excess tax benefit is the amount by which the Company’s tax deduction for these awards, based on the fair market value of the awards on the date of vesting, exceeds the expense recorded in the Company’s financial statements over the awards’ vesting period. In accordance with Staff Accounting Bulletin No. 118 (“SAB 118”), we did not record any adjustment in the quarter to the provisional tax expense on accumulated foreign earnings (the “Transition Tax”) recorded during the fiscal year ended April 30, 2018 after the enactment of the Tax Act. This provisional expense may be adjusted in subsequent periods based on additional guidance that may be issued by the U.S. Treasury Department, the Internal Revenue Service (“IRS”) and other standard-setting bodies. The Company will continue to appropriately analyze and, if necessary, adjust this amount within the measurement period provided under SAB 118, with the analysis to be completed no later than December 22, 2018. The Company also continues to evaluate the impact of the Global Intangible Low-Taxed Income (“GILTI”), Foreign Derived Intangible Income (“FDII”), Base Erosion and Anti-Abuse Tax (“BEAT”), the change to the IRC Section 162(m) limitation (the “Executive Compensation Limitation”) and IRC Section 163 (j) interest limitation (the “Interest Limitation”) provisions of the Tax Act which is complex and subject to continuing regulatory interpretation. In accordance with SAB 118, we recorded a provisional estimate in our effective tax rate for the three and six months ended October 31, 2018 for GILTI, FDII and the Executive Compensation Limitation. For BEAT and the Interest Limitation computations, we did not record a provisional estimate in our effective tax rate for the three and six months ended October 31, 2018 because we currently estimate that these provisions will not affect our tax expense in the current fiscal year. We will continue to refine our provisional estimates for the GILTI, FDII, BEAT, Executive Compensation Limitation and Interest Limitation computations as we gather additional information and receive additional guidance from standard-setting bodies. The Company is required to make an accounting policy election of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the “period cost method”) or (2) factoring such amounts in the Company’s measurement of its deferred taxes (the “deferred method”). The Company’s accounting policy election with respect to the new GILTI rules will depend, in part, on analyzing its global income to determine whether it can reasonably estimate the tax impact. In accordance with SAB 118, the Company is continuing with its analysis and will finalize the election in the following quarter.

Business Segments	9. Business Segments The Company currently operates in three global businesses: Executive Search, Advisory and RPO & Professional Search. The Executive Search segment focuses on recruiting board level, chief executive and other senior executive and general management positions The Company evaluates performance and allocates resources based on the Company’s chief operating decision maker’s review of (1) fee revenue and (2) adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”). To the extent that such charges occur, Adjusted EBITDA excludes restructuring charges, integration/acquisition costs, certain separation costs and certain non-cash charges (goodwill, intangible asset and other than temporary impairment). The accounting policies for the reportable segments are the same as those described in the summary of significant accounting policies, except the items described above are excluded from EBITDA to arrive at Adjusted EBITDA.

Long-Term Debt

Long-Term Debt	6 Months Ended

Debt Disclosure [Abstract]
Long-Term Debt	10. Long-Term Debt On June 15, 2016, the Company entered into a senior secured $400.0 million Credit Agreement (the “Credit Agreement”) with a syndicate of banks and Wells Fargo Bank, National Association as administrative agent. On June 8, 2018, in anticipation of the approval by the Board of Directors of the Company of a rebranding and restructuring plan (which plan was approved on June 12, 2018), the Company entered into an amendment to its Credit Agreement. The Amendment permits a holding company reorganization (the “KF Merger”), after which a new public holding company, Korn Ferry, will own all of the stock of the Company, and will become effective when certain conditions set forth therein, including consummation of the KF Merger, are satisfied. The Company previously considered pursuing the KF Merger as part of the Plan. While the Company continues to pursue the Plan, it is further evaluating various other structuring alternatives to effectuate the Plan but may not do so via the KF Merger structure previously disclosed. The Credit Agreement provides for, among other things: (a) a senior secured term loan facility in an aggregate principal amount of $275.0 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 $125.0 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 to Adjusted EBITDA in recognition of the accelerated integration actions. The Company’s credit agreement permits payment of dividends to stockholders and share repurchases so long as the pro forma leverage ratio is no greater than 2.50 to 1.00, and the pro forma domestic liquidity is at least $50.0 million. The Company drew down $275.0 million on the new term loan and used $140.0 million of the proceeds to pay-off the term loan that was outstanding as of April 30, 2016. 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, 2018, the average rate on the Term Facility was 3.39% and 3.31%, respectively. During the three and six months ended October 31, 2017, the average rate on the Term Facility was 2.49% and 2.41%, 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 totaling $12.0 million made during the six months ended October 31, 2018. As of October 31, 2018, $226.9 million was outstanding under the Term Facility compared to $238.9 million as of April 30, 2018. The current and long-term portion of unamortized debt issuance costs associated with the long-term debt, was $2.3 million and $2.7 million as of October 31, 2018 and April 30, 2018, 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, 2018, the Company was in compliance with its debt covenants. As of October 31, 2018 and April 30, 2018, the Company had no borrowings under the Revolver. The Company had a total of $122.1 million available under the Revolver after $2.9 million of standby letters of credit were issued as of October 31, 2018 and April 30, 2018, respectively. The Company had a total of $8.1 million and $7.4 million of standby letters with other financial institutions of October 31, 2018 and April 30, 2018, respectively. The standby letters of credits were generally issued as a result of entering into office premise leases.

Accounting Policies [Abstract]
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 for the year ended April 30, 2018 for the Company and its wholly and majority owned/controlled domestic and international subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The preparation of the consolidated financial statements conform with United States (“U.S.”) generally accepted accounting principles (“GAAP”) and prevailing practice within the industry. The consolidated financial statements include all adjustments, consisting of normal recurring accruals and any other adjustments that management considers necessary for a fair presentation of the results for these periods. The results of operations for the interim period are not necessarily indicative of the results for the entire fiscal year. 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 or determinable. The most significant areas that require management’s judgment are revenue recognition, deferred compensation, annual performance related bonuses, evaluation of the carrying value of receivables, goodwill and other intangible assets, share-based payments and the recoverability of deferred income taxes.
Revenue Recognition	Revenue Recognition either Revenue is recognized when control of the goods and services are transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods and services. Revenue contracts with customers are evaluated based on the five-step model outlined in Accounting Standard Codification 606 (“ASC 606”): 1) identify the contract with a customer; 2) identify the performance obligation(s) in the contract; 3) determine the transaction price; 4) allocate the transaction price to the separate performance obligation(s); and 5) recognize revenue when (or as) each performance obligation is satisfied. Fee revenue from executive and non-executive professional search activities is generally one-third of the estimated first year compensation of the placed candidate plus a percentage of the fee to cover RPO fee Consulting fee revenue, primarily generated from Advisory, is recognized as services are rendered, measured by total hours incurred to the total estimated hours at completion. It is possible that updated estimates for consulting engagements may vary from initial estimates with such updates being recognized in the period of determination. Depending on the timing of billings and services rendered, the Company accrues or defers revenue as appropriate. Product revenue is generated from a range of online tools designed to support human resource processes for pay, talent and engagement, assessments, as well as licenses to proprietary intellectual property (“IP”) and tangible/digital products. IP Functional IP licenses grant customers the right to use IP content via delivery of a flat file. Because the IP content license has significant standalone functionality, revenue is recognized upon delivery and when an enforceable right to payment exists . Online assessments are delivered in the form of online questionnaires. A bundle of assessments represents one performance obligation, and revenue is recognized as assessment services are delivered and the Company has a legally enforceable right to payment.
Reimbursements	Reimbursements The Company incurs certain out-of-pocket expenses that are reimbursed by its clients, which are accounted for as revenue in its consolidated statements of income.
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, 2018 and April 30, 2018, 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 (for which market prices are readily available) that 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 set of securities and the Company invests in marketable securities to mirror these elections. These investments are recorded at fair value with the change in value in the period being reflected in the consolidated statements of income and are classified as marketable securities in the accompanying consolidated balance sheets. The investments that the Company may sell within the next twelve months are carried as current assets. Realized gains (losses) on marketable securities are determined by specific identification. Interest is recognized on an accrual basis; dividends are recorded as earned on the ex-dividend date. Interest, dividend income and the changes in fair value in marketable securities are recorded in the accompanying consolidated statements of income in other (loss) income, net.
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: Observable inputs such as quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. ▪ Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. ▪ Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions. As of October 31, 2018 and April 30, 2018, 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 an interest rate swap. The carrying amount of cash, cash equivalents and accounts receivable approximates fair value due to the short-term maturity of these instruments. The fair values of marketable securities are obtained from quoted market prices, and the fair values of foreign currency forward contracts and 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 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 primarily originating from intercompany balances due to cross border work performed in the ordinary course of business. 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, 2018, 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, 2018 and April 30, 2018 that would have required further testing. Intangible assets primarily consist of customer lists, non-compete agreements, proprietary databases and intellectual property. Intangible assets are recorded at their estimated fair value at the date of acquisition and are amortized in a pattern in which the asset is consumed if that pattern can be reliably determined, or using the straight-line method over their estimated useful lives which range from one to 24 years. For intangible assets subject to amortization, an impairment loss is recognized if the carrying amount of the intangible assets is not recoverable and exceeds fair value. The carrying amount of the intangible assets is considered not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from use of the asset. Intangible assets with indefinite lives are not amortized, but are reviewed annually for impairment or more frequently whenever events or changes in circumstances indicate that the fair value of the asset may be less than its carrying amount. As of October 31, 2018 and April 30, 2018, there were no further indicators of impairment with respect to the Company’s intangible assets, with the exception of the intangible asset impairment charge discussed below. On June 12, 2018, the Company’s Board of Directors voted to approve a rebranding plan with the Company going to market under a single, master brand architecture, solely as Korn Ferry and sunsetting of all the Company’s sub-brands, including Futurestep, Hay Group and Lominger, among others. This integrated go-to-market approach was a key driver in our fee revenue growth in fiscal 2018, which led to the decision to further integrate our go-to-market activities under one master brand – Korn Ferry. As a result, the Company discontinued the use of all sub-brands. Two of the Company’s sub-brands, Hay Group and Lominger came to Korn Ferry through acquisitions. In connection with the accounting for these acquisitions, $106.6 million of the purchase price was allocated to indefinite lived tradename intangible assets. As a result of the decision to discontinue their use, the Company took a non-cash intangible asset impairment charge of $106.6 million, during the six months ended October 31, 2018 recorded in general and administrative expenses. No impairment charge was recorded during the three months ended October 31, 2018.
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 Advisory and RPO and Professional Search 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 and 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 $142.9 million and $98.5 million during the six months ended October 31, 2018 and 2017, respectively, included in compensation and benefits expense in the consolidated statements of income. During the three months ended October 31, 2018 and 2017, the performance related bonus was $81.9 million and $56.9 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. Unearned compensation on the consolidated balance sheets includes 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 employee termination benefits and the cost to terminate an office lease including remaining lease payments. Changes in the estimates of the restructuring charges are recorded in the period the change is determined.
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 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 purchases under the ESPP on a straight-line basis over the service period for the entire award.
Reclassifications	Reclassifications Certain reclassifications have been made to the amounts in prior periods in order to conform to the current period’s presentation.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (“ FASB”) issued ASC 606, which superseded revenue recognition requirements regarding contracts with customers to transfer goods or services The Company recognized the cumulative effect of initially applying the new guidance as an adjustment to the opening balance of retained earnings. The comparative periods have not been restated and continue to be reported under the revenue accounting standards in effect for those periods. As a result of the adoption, the Company recorded an increase to retained earnings of $6.7 million, net of tax as of May 1, 2018 due to the cumulative impact of adopting ASC 606. The change in total assets was recorded to unbilled receivables which is included in receivables due from clients; the changes in total liabilities was recorded to income taxes payable, deferred tax liabilities and deferred revenue, which is included in other accrued liabilities. The following table summarizes the effect of changes made to our consolidated balance sheet at May 1, 2018: Adjustments April 30, 2018 due to ASC 606 May 1, 2018 (in thousands) Total assets $ 2,287,914 $ 3,496 $ 2,291,410 Total liabilities $ 1,068,299 $ (3,160 ) $ 1,065,139 Total stockholders’ equity $ 1,219,615 $ 6,656 $ 1,226,271 term licenses and revenue was recognized ratably over the contract term. 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 and were adopted by the Company effective May 1, 2018. The adoption of this guidance did not have an impact on the Company’s 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 to be applied prospectively. The provisions of the guidance are effective for annual years beginning after December 15, 2017 and were adopted by the Company effective May 1, 2018. The adoption of this guidance did not have an impact on the Company’s 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. This pronouncement is effective for annual reporting periods beginning after December 15, 2017 and was adopted by the Company effective May 1, 2018. The change to the c onsolidated statements of income Prior period amounts were revised, which resulted in a decrease in compensation expense and other income of $2.4 million and $0.4 million, respectively, and an increase in interest expense of $2.1 million in the six months ended October 31, 2017. During the three months ended October 31, 2017 prior period amounts were revised, which resulted in a decrease in compensation expense and other income of $1.2 million and $0.2 million, respectively, and an increase in interest expense of $1.0 million (see Note 6 — Deferred Compensation and Retirement Plans ). 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 and was adopted by the Company effective May 1, 2018. The adoption of this guidance did not have an impact on the Company’s consolidated financial statements. Any future impact of this guidance will be dependent on future modification including the number of awards modified. Cuts and Jobs Act of 2017 (the ” Tax Act”) from
Recently Proposed Accounting Standards - Not Yet Adopted	Recently Proposed Accounting Standards – Not Yet Adopted 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. On July 30, 2018, the FASB issued an amendment that allows entities to apply the provisions at the effective date without adjusting comparative periods. 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 assets and lease liabilities related to lease agreements. 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 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 situations. 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. In August 2018, the FASB issued guidance amending the disclosure requirements for fair value measurements. The amendment removes and modifies disclosures that are currently required and adds additional disclosures that are deemed relevant. The amendments of this standard are effective for fiscal years beginning after December 15, 2019. The Company will adopt this guidance in its fiscal year beginning May 1, 2020. In August 2018, the FASB issued guidance amending accounting for internal-use software. The new guidance will align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with developing or obtaining internal-use software. The amendments of this standard are effective for fiscal years ending after December 15, 2019 with early adoption permitted. The Company will adopt this guidance in its fiscal year beginning May 1, 2020. The Company is currently evaluating the impact of adopting this guidance. In August 2018, the FASB issued guidance amending and modifying the disclosure requirements for employers that sponsor defined benefit pension or other postretirement pension plans. The amendment removes disclosures to pension plans and other postretirement benefit plans that are no longer considered beneficial and adds disclosure requirements deemed relevant. The amendments of this standard are effective for fiscal years ending after December 15, 2020. The Company will adopt this guidance in its fiscal year beginning May 1, 2021. The Company is currently evaluating the impact of adopting this guidance.
