The Company will apply the transition requirements at the February 1, 2019 effective date by showing a cumulative effect adjustment in the first quarter of fiscal 2020, rather than restating any prior periods.

The Company is in the process of finalizing its calculation and testing of the third-party software solution and estimates recording right-of-use assets and lease liabilities in the range of $80 million to $100 million. The standard is not expected to have a significant impact on the Company’s consolidated results of operations or cash flows. On August 28, 2017, FASB issued ASU 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities,” which expands an entity’s ability to apply hedge accounting for nonfinancial and financial risk components and allows for a simplified approach for fair value hedging of interest rate risk. The new guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The new guidance also simplifies the hedge documentation and effectiveness assessment requirements. For public companies, the standard will be effective for the first interim reporting period within annual periods beginning after December 15, 2018, which will be the Company’s first quarter of fiscal 2020, with early adoption permitted.
