These statements, which include words such as “believes”, “expects” or “likely”, include references to our outlook. Readers are cautioned not to place undue reliance on such statements. Actual results in future periods may differ materially from those currently expected or desired because of a number of risks and uncertainties that are beyond the control of Korn Ferry.

Use of Non-GAAP Financial Measures

This press release contains financial information calculated other than in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). In particular, it includes:

This non-GAAP disclosure has limitations as an analytical tool, should not be viewed as a substitute for financial information determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of the Company’s results as reported under GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies.

Management believes the presentation of non-GAAP financial measures in this press release provides meaningful supplemental information regarding Korn Ferry’s performance by excluding certain charges and other items that may not be indicative of Korn Ferry’s ongoing operating results. These non-GAAP financial measures are performance measures and are not indicative of the liquidity of Korn Ferry. These charges represent 1) the tax impact associated with the Tax Act, 2) costs we incurred to acquire and integrate the Legacy Hay acquisition, 3) charges we incurred to restructure the combined company due to the acquisition of Legacy Hay, 4) debt issuance costs written-off upon replacement of our credit facility and 5) revenue that Hay Group would have realized if not for business combination accounting that requires a company to record the acquisition balance sheet at fair value and write-off deferred revenue where no future services are required to be performed to earn that revenue. As such, reported fee revenue can make fee revenue and operating results appear to fluctuate more than they would if business combination accounting did not require deferred revenue to be written off. Adjusted fee revenue is not a measure that substitutes an individually tailored revenue recognition or measurement method for those of GAAP, rather, it is an adjustment for a short period of time that will provide better comparability in the current and future periods. Management believes the presentation of adjusted fee revenue assists management in its evaluation of ongoing operations and provides useful information to investors because it allows investors to make more meaningful period-to-period comparisons of the Company’s operating results, to better identify operating trends that may otherwise be distorted by write-offs required under business combination accounting and to perform related trend analysis, and provides a higher degree of transparency of information used by management in its evaluation of Korn Ferry’s ongoing operations and financial and operational decision-making. Management no longer has adjusted fee revenue after Q1 FY’17. The use of non-GAAP financial measures facilitates comparisons to Korn Ferry’s historical performance. Korn Ferry includes non-GAAP financial measures because management believes they are useful to investors in allowing for greater transparency with respect to supplemental information used by management in its evaluation of Korn Ferry’s ongoing operations and financial and operational decision-making. Management further believes that EBITDA is useful to investors because it is frequently used by investors and other interested parties to measure operating performance among companies with different capital structures, effective tax rates and tax attributes and capitalized asset values, all of which can vary substantially from company to company. In the case of constant currency amounts, management believes the presentation of such information provides useful supplemental information regarding Korn Ferry’s performance as excluding the impact of exchange rate changes on Korn Ferry’s financial performance allows investors to make more meaningful period-to-period comparisons of the Company’s operating results, to better identify operating trends that may otherwise be masked or distorted by exchange rate changes and to perform related trend analysis, and provides a higher degree of transparency of information used by management in its evaluation of Korn Ferry’s ongoing operations and financial and operational decision-making.
