Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	1. Organization and Summary of Significant Accounting Policies Nature of Business Korn Ferry, a Delaware corporation (the “Company”), and its subsidiaries currently operate through three global segments: Korn Ferry Advisory (“Advisory”), Executive Search and Korn Ferry RPO and Professional Search (“RPO & Professional Search”). Advisory assists clients to synchronize strategy and talent by addressing four fundamental needs: Organizational Strategy, Assessment and Succession, Leadership Development, and Rewards and Benefits, all underpinned by a comprehensive array of some of the world’s leading intellectual property (“IP”), products and tools. Executive Search focuses on recruiting board level, chief executive and other senior executive and general management positions, in addition to research-based interviewing and assessment solutions, for clients predominantly in the consumer goods, financial services, industrial, life sciences/healthcare and technology industries. RPO & Professional Search uses data-backed insight and IP, matched with strategic collaboration and innovative technology, to meet people challenges head-on—and succeed. Solutions span all aspects of Recruitment Process Outsourcing (“RPO”), Professional Search and Project Recruitment. 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, 2019 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 Mexico partners’ 51% 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, leases, and the recoverability of deferred income taxes. Revenue Recognition Substantially all fee revenue is derived from talent and organizational advisory services and the digital sales, fees for professional services related to executive and professional recruitment performed on a retained basis and RPO, 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. 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. Digital revenue is generated from a range of online tools designed to support human resource processes for pay, talent and engagement, and assessments, as well as licenses to proprietary 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 stand-alone 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. Fee revenue from executive and professional search activities is generally one-third of the estimated first-year cash compensation of the placed candidate, plus a percentage of the fee to cover RPO fee Reimbursements The Company incurs certain out-of-pocket expenses that are reimbursed by its clients, which are accounted for as revenue in the 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 and 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 from the date of purchase to be cash equivalents. As of October 31, 2019 and April 30, 2019, the Company’s investments in cash equivalents consisted 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 income (loss), 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, 2019 and April 30, 2019, 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 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 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 ASC 815. Accordingly, the fair value of these contracts is recorded as of the end of the reporting period in the accompanying consolidated balance sheets, while the change in fair value is recorded to the accompanying consolidated statements of income. 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. Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of use (“ROU”) assets and current and non-current operating lease liability, in the consolidated balance sheets. Finance leases are included in property and equipment, net, other accrued liabilities and other liabilities in the consolidated balance sheets. ROU assets represent the Company's right to use an underlying asset for the lease term, and the lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate, the Company uses its estimated incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term, with variable lease payments recognized in the periods in which they are incurred. The Company has lease agreements with lease and non-lease components. For all leases with non-lease components the Company accounts for the lease and non-lease components as a single lease component. 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, 2019, 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, 2019 and April 30, 2019 that required further testing. Intangible assets primarily consist of customer lists, non-compete agreements, proprietary databases and IP. 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 indicated that the fair value of the asset may be less than its carrying amount. As of October 31, 2019 and April 30, 2019, there were no indicators of impairment with respect to the Company’s intangible assets. On June 12, 2018, the Company’s Board of Directors voted to approve a plan to go to market under a single, master brand architecture and to simplify the Company’s organizational structure by eliminating and/or consolidating certain legal entities and implementing a rebranding of the Company to offer the Company’s current products and services using the “Korn Ferry” name, branding and trademarks. As a result, the Company discontinued the use of all sub-brands. Two of the Company’s former 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 write-off of $106.6 million during the six months ended October 31, 2018, recorded in general and administrative expenses. 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 & Professional Search consultants), the level of engagements referred by a consultant in one line of business to a different line of business, and 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 $117.4 million and $142.9 million during the six months ended October 31, 2019 and 2018, respectively, included in compensation and benefits expense in the consolidated statements of income. During the three months ended October 31, 2019 and 2018, the performance related bonus expense was $64.4 million and $81.9 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. 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 February 2016, the Financial Accounting Standards Board (“FASB”) issued guidance (Accounting Standard Codification 842 – Leases Leases . The adoption of this standard had a material impact on the consolidated balance sheet as of October 31, 2019 due to the recognition of ROU assets and operating lease liabilities, but an immaterial impact on the Company’s consolidated statements of income, consolidated statements of stockholders’ equity, and consolidated statements of cash flows. Upon adoption we recognized total ROU assets of $236.1 million with a corresponding liability of $272.3 million. The ROU asset balance was adjusted by the reclassification of pre-existing prepaid expenses and other assets and deferred rent balances of $5.1 million and $41.3 million, respectively. In August 2017, the FASB issued guidance amending and simplifying accounting for hedging activities. The guidance refined and expanded strategies that qualify for hedge accounting and simplify the application of hedge accounting in certain situations. The guidance is effective for fiscal years beginning after December 15, 2018. The Company adopted this guidance in its fiscal year beginning May 1, 2019. The adoption of this guidance did not have an impact on the consolidated financial statements. Recently Proposed Accounting Standards - Not Yet Adopted In June 2016, the FASB issued guidance on accounting for measurement of credit losses on financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables. The standard is effective for fiscal years beginning after December 15, 2019. The Company will adopt this guidance in its fiscal year beginning May 1, 2020. 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 doesn’t anticipate the guidance to have a material impact on the consolidated financial statements. 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.

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, 2019, restricted stock awards of 0.7 million were outstanding, but not included in the computation of diluted earnings per share because they were anti-dilutive. During the three and six months ended October 31, 2018, 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 Fourth A&R 2008 Plan was also amended to generally require a minimum one-year Restricted Stock The Company grants time-based restricted stock awards to executive officers and other senior employees generally vesting over a four-year The Company also grants market-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. Restricted stock activity during the six months ended October 31, 2019 is summarized below: Shares Weighted- Average Grant Date Fair Value (in thousands, except per share data) Non-vested, April 30, 2019 1,460 $ 38.42 Granted 586 $ 38.31 Vested (615 ) $ 25.06 Forfeited/expired (21 ) $ 20.86 Non-vested, October 31, 2019 1,410 $ 44.47 As of October 31, 2019, there were 0.5 million shares outstanding relating to market-based restricted stock units with total unrecognized compensation totaling $15.4 million. As of October 31, 2019, there was $46.4 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 2.5 years.

As of October 31, 2019 and April 30, 2019, the Company’s investments in marketable securities consisted of mutual funds for which market prices are readily available. 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. As of October 31, 2019, the notional amount was $99.7 million. The interest rate swap agreement matures on June 15, 2021, and locks the interest rates on a portion of 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 was as follows: October 31, 2019 April 30, 2019 (in thousands) Derivative asset: Interest rate swap contract $ — $ 619 Derivative liability: Interest rate swap contract $ 666 $ — During the three and six months ended October 31, 2019 and 2018, the Company recognized the following gains and losses on the interest rate swap: Three Months Ended October 31, Six Months Ended October 31, 2019 2018 2019 2018 (in thousands) (Losses) gains recognized in other comprehensive income (net of tax effects of $(111), $67, $(283) and $120, respectively) $ (315 ) $ 193 $ (806 ) $ 342 Gains reclassified from accumulated other comprehensive income into interest expense, net $ 55 $ 64 $ 196 $ 86 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 $0.4 million of derivative losses included in accumulated other comprehensive income (loss) as of October 31, 2019 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, 2019 April 30, 2019 (in thousands) Derivative assets: Foreign currency forward contracts $ 1,301 $ 821 Derivative liabilities: Foreign currency forward contracts $ 548 $ 722 As of October 31, 2019, the total notional amounts of the forward contracts purchased and sold were $55.1 million and $47.9 million, respectively. As of April 30, 2019, the total notional amounts of the forward contracts purchased and sold were $51.4 million and $40.0 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 and six months ended October 31, 2019, the Company incurred gains of $2.1 million and $0.5 million, respectively, related to forward contracts, which is recorded in general and administrative expenses in the accompanying consolidated statements of income. These foreign currency gains offset foreign currency losses that result from transactions denominated in a currency other than the Company’s functional currency.

Leases [Abstract]
Leases	6. Leases The Company’s lease portfolio is comprised of operating leases for office space and equipment and finance leases for equipment. Equipment leases are comprised of vehicles and office equipment. The majority of the Company’s leases include both lease and non-lease components. Non-lease components primarily include maintenance, insurance, taxes and other utilities. The Company has decided to combine fixed payments for non-lease components with its lease payments and account for them as a single lease component, which increases its ROU assets and lease liabilities. Some of the leases include one or more options to renew or terminate the lease at the Company’s discretion. Generally, the renewal and termination options are not included in the ROU assets and lease liabilities as they are not reasonably certain of exercise. The Company has elected not to recognize a ROU asset or lease liability for leases with an initial term of 12 months or less. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of the future minimum lease payments. The Company applies the portfolio approach when determining the incremental borrowing rate since it has a centrally managed treasury function. The Company’s incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments in a similar economic environment. Operating leases contain both office and equipment leases, have remaining terms that range from less than one year to 11 years, some of which also include options to extend or terminate the lease. Finance leases are comprised of equipment leases and have remaining terms that range from less than one year to 5 years. Finance lease assets are included in property and equipment, net while finance lease liabilities are included in other accrued liabilities and other liabilities. The components of lease expense were as follows: Three Months Ended October 31, 2019 Six Months Ended October 31, 2019 (in thousands) Finance lease cost Amortization of ROU assets $ 473 $ 943 Interest on lease liabilities 39 79 512 1,022 Operating lease cost 14,166 28,393 Short-term lease cost 277 556 Variable lease cost 3,183 6,076 Sublease income (53 ) (107 ) Total lease cost $ 18,085 $ 35,940 Supplemental cash flow information related to leases was as follows: Six Months Ended October 31, 2019 (in thousands) Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 30,351 Financing cash flows from finance leases $ 927 ROU assets obtained in exchange for lease obligations: Operating leases $ 6,054 Finance leases $ 732 Supplemental balance sheet information related to leases was as follows: October 31, 2019 (in thousands) Finance Leases: Property and equipment, at cost $ 4,586 Accumulated depreciation (930 ) Property and equipment, net $ 3,656 Other accrued liabilities $ 1,597 Other liabilities 2,107 Total finance lease liabilities $ 3,704 Weighted average remaining lease terms: Operating leases 6.0 years Finance leases 2.7 years Weighted average discount rate: Operating leases 4.9 % Finance leases 4.2 % Maturities of lease liabilities were as follows: Year Ending April 30, Operating Financing (in thousands) 2020 (excluding the six months ended October 31, 2019) $ 30,609 $ 930 2021 55,843 1,466 2022 48,661 1,003 2023 41,648 365 2024 35,904 132 Thereafter 75,748 18 Total lease payments 288,413 3,914 Less: imputed interest 39,654 210 Total $ 248,759 $ 3,704

Compensation And Retirement Disclosure [Abstract]
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 employees in the U.S.. The assets of this plan are held separately from the assets of the sponsor 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, 2019 2018 2019 2018 (in thousands) Service cost $ 6,474 $ 4,532 $ 11,930 $ 8,178 Interest cost 1,422 1,330 2,815 2,626 Amortization of actuarial loss 745 446 1,490 892 Expected return on plan assets (1) (363 ) (392 ) (726 ) (784 ) Net periodic service credit amortization (77 ) (77 ) (154 ) (154 ) Net periodic benefit costs (2) $ 8,201 $ 5,839 $ 15,355 $ 10,758 (1) The expected long-term rate of return on plan assets was 6.00 % and 6.25 % for October 31, 2019 and 2018, 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 income (loss), 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 $220.9 and $219.2 million as of October 31, 2019 and April 30, 2019, 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 consolidated balance sheets. 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, 2019, deferred compensation liability increased; therefore, the Company recognized compensation expense of $1.3 million and $3.5 million, respectively. Offsetting the increases in compensation and benefits expense was an increase in the fair value of marketable securities (held in trust to satisfy obligations of the ECAP liabilities) of $1.2 million and $3.1 million during the three and six months ended October 31, 2019, respectively, recorded in other income (loss), net on the consolidated statements of income. 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 income (loss), net on the consolidated statements of income Financial Instruments

Revenue From Contract With Customer [Abstract]
Fee Revenue	8. Fee Revenue Substantially all fee revenue is derived from talent and organizational advisory services and digital sales, fees for professional services related to executive and professional recruitment performed on a retained basis and RPO, standalone or as part of a solution. 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, 2019 and April 30, 2019: October 31, 2019 April 30, 2019 (in thousands) Contract assets (unbilled receivables) $ 78,391 $ 60,595 Contract liabilities (deferred revenue) $ 115,630 $ 112,999 During the six months ended October 31, 2019, we recognized revenue of $69.0 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, 2019, 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 $608.3 million. Of the $608.3 million of remaining performance obligations, the Company expects to recognize approximately $203.4 million as fee revenue in fiscal 2020, $209.1 million in fiscal 2021, $117.4 million in fiscal 2022 and the remaining $78.4 million in fiscal 2023 and thereafter Disaggregation of Revenue The Company disaggregates its revenue by line of business and further by region for Executive Search.

Segment Reporting [Abstract]
Segments	10. Segments The Company currently operates through three global business segments: Advisory, Executive Search and RPO & Professional Search. Advisory assists clients to synchronize strategy and talent by addressing four fundamental needs: Organizational Strategy, Assessment and Succession, Leadership Development and Rewards and Benefits, all underpinned by a comprehensive array of some of the world’s leading IP, products and tools. Executive Search 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).

Debt Disclosure [Abstract]
Long-Term Debt	11. Long-Term Debt On December 19, 2018, the Company entered into an Amended and Restated Credit Agreement (the “Credit Agreement”) with a syndicate of banks and Wells Fargo Bank, National Association as administrative agent to among other things, provide for enhanced financial flexibility. The Credit Agreement provides for, among other things: (a) a $650.0 million five-year The principal balance of the Revolver is due on the date of its termination. The Revolver matures on December 19, 2023 and any unpaid principal balance is payable on this date. The Revolver may also be prepaid and terminated early by the Company at any time without premium or penalty (subject to customary LIBOR breakage fees). 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 Agreement 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 commitment fee ranging from 0.20% to 0.35% per annum on the average daily unused amount of the Revolver, 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, 2019, the average interest rate on our long-term debt arrangements was 3.37% and 3.53%, respectively. During the three and six months ended October 31, 2018, the average interest rate on our long-term debt arrangements was 3.39% and 3.31%, respectively. As of October 31, 2019, $276.9 million was outstanding under the Revolver compared to $226.9 million as of April 30, 2019. The unamortized debt issuance costs associated with the long-term debt were $3.6 million and $4.0 million as of October 31, 2019 and April 30, 2019, respectively. The fair value of the Company’s Revolver is based on borrowing rates currently required of loans with similar terms, maturity and credit risk. The carrying amount of the Revolver 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 Revolver is classified as a Level 2 liability in the fair value hierarchy. As of October 31, 2019, the Company was in compliance with its debt covenants. The Company had a total of $369.9 million available under the Revolver after the Company drew down $276.9 million and after $3.2 million of standby letters of credit were issued as of October 31, 2019. The Company had a total of $420.2 million available under the Revolver after the Company drew down $226.9 million and after $2.9 million of standby letters of credit were issued as of April 30, 2019. The Company had a total of $11.0 million and $8.5 million of standby letters with other financial institutions as of October 31, 2019 and April 30, 2019, respectively. The standby letters of credits were generally issued as a result of entering into office premise leases.

Subsequent Events [Abstract]
Subsequent Event	12. Subsequent Event Quarterly Dividend Declaration On December 4, 2019, the Board of Directors of the Company declared a cash dividend of $0.10 per share with a payment date of January 15, 2020 to holders of the Company’s common stock of record at the close of business on December 20, 2019. The declaration and payment of future dividends under the quarterly dividend policy will be at the discretion of the Board of Directors and will depend upon many factors, including the Company’s earnings, capital requirements, financial conditions, the terms of the Company’s indebtedness and other factors that the Board of Directors may deem to be relevant. The Board of Directors may amend, revoke or suspend the dividend policy at any time and for any reason. Restructuring On November 1, 2019, the “Company adopted a restructuring plan relating to actions in respect to the integration of the recently completed acquisitions. The purpose of this plan is to rationalize the Company’s cost structure as a result of efficiencies and operational improvements that the Company will be positioned to realize upon integration of the Acquired Entities into the Company. The plan will include the elimination of redundant positions and consolidation of office space. The estimated cost of the actions contemplated by the plan is between $20.0 million to $26.0 million, of which $18.0 million to $ 22.0 million relates to severance and $ 2.0 million to $ 4.0 million relates to office consolidation and abandonment of premises. These charges are expected to include approximately $ 18.0 million to $ 24.0 million of cash expenditures. The Company expects to recognize these charges between the three months ended January 31, 2020 and the three months ended July 31, 2020 and expects the restructuring actions to be completed by July 31, 2020.

Organization and Summary of Significant Accounting Policies (Policies)	6 Months Ended

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, 2019 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 Mexico partners’ 51% 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, leases, and the recoverability of deferred income taxes.
Revenue Recognition	Revenue Recognition Substantially all fee revenue is derived from talent and organizational advisory services and the digital sales, fees for professional services related to executive and professional recruitment performed on a retained basis and RPO, 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. 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. Digital revenue is generated from a range of online tools designed to support human resource processes for pay, talent and engagement, and assessments, as well as licenses to proprietary 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 stand-alone 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. Fee revenue from executive and professional search activities is generally one-third of the estimated first-year cash compensation of the placed candidate, plus a percentage of the fee to cover RPO fee
Reimbursements	Reimbursements The Company incurs certain out-of-pocket expenses that are reimbursed by its clients, which are accounted for as revenue in the 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 and 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 from the date of purchase to be cash equivalents. As of October 31, 2019 and April 30, 2019, the Company’s investments in cash equivalents consisted 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 income (loss), 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, 2019 and April 30, 2019, 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 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 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 ASC 815. Accordingly, the fair value of these contracts is recorded as of the end of the reporting period in the accompanying consolidated balance sheets, while the change in fair value is recorded to the accompanying consolidated statements of income.
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.
Leases	Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of use (“ROU”) assets and current and non-current operating lease liability, in the consolidated balance sheets. Finance leases are included in property and equipment, net, other accrued liabilities and other liabilities in the consolidated balance sheets. ROU assets represent the Company's right to use an underlying asset for the lease term, and the lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate, the Company uses its estimated incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term, with variable lease payments recognized in the periods in which they are incurred. The Company has lease agreements with lease and non-lease components. For all leases with non-lease components the Company accounts for the lease and non-lease components as a single lease component.
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, 2019, 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, 2019 and April 30, 2019 that required further testing. Intangible assets primarily consist of customer lists, non-compete agreements, proprietary databases and IP. 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 indicated that the fair value of the asset may be less than its carrying amount. As of October 31, 2019 and April 30, 2019, there were no indicators of impairment with respect to the Company’s intangible assets. On June 12, 2018, the Company’s Board of Directors voted to approve a plan to go to market under a single, master brand architecture and to simplify the Company’s organizational structure by eliminating and/or consolidating certain legal entities and implementing a rebranding of the Company to offer the Company’s current products and services using the “Korn Ferry” name, branding and trademarks. As a result, the Company discontinued the use of all sub-brands. Two of the Company’s former 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 write-off of $106.6 million during the six months ended October 31, 2018, recorded in general and administrative expenses.
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 & Professional Search consultants), the level of engagements referred by a consultant in one line of business to a different line of business, and 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 $117.4 million and $142.9 million during the six months ended October 31, 2019 and 2018, respectively, included in compensation and benefits expense in the consolidated statements of income. During the three months ended October 31, 2019 and 2018, the performance related bonus expense was $64.4 million and $81.9 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.
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 February 2016, the Financial Accounting Standards Board (“FASB”) issued guidance (Accounting Standard Codification 842 – Leases Leases . The adoption of this standard had a material impact on the consolidated balance sheet as of October 31, 2019 due to the recognition of ROU assets and operating lease liabilities, but an immaterial impact on the Company’s consolidated statements of income, consolidated statements of stockholders’ equity, and consolidated statements of cash flows. Upon adoption we recognized total ROU assets of $236.1 million with a corresponding liability of $272.3 million. The ROU asset balance was adjusted by the reclassification of pre-existing prepaid expenses and other assets and deferred rent balances of $5.1 million and $41.3 million, respectively. In August 2017, the FASB issued guidance amending and simplifying accounting for hedging activities. The guidance refined and expanded strategies that qualify for hedge accounting and simplify the application of hedge accounting in certain situations. The guidance is effective for fiscal years beginning after December 15, 2018. The Company adopted this guidance in its fiscal year beginning May 1, 2019. The adoption of this guidance did not have an impact on the consolidated financial statements.
Recently Proposed Accounting Standards - Not Yet Adopted	Recently Proposed Accounting Standards - Not Yet Adopted In June 2016, the FASB issued guidance on accounting for measurement of credit losses on financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables. The standard is effective for fiscal years beginning after December 15, 2019. The Company will adopt this guidance in its fiscal year beginning May 1, 2020. 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 doesn’t anticipate the guidance to have a material impact on the consolidated financial statements. 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.
