The updated accounting guidance clarifies the principles for recognizing revenue and provides a single, contract-based revenue recognition model in order to create greater comparability for financial statement users across industries and jurisdictions. The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to clients in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

The adoption of ASU 2014-09 has an immaterial impact on the timing of revenue recognition and did not have a significant impact on the Company’s consolidated financial statements.

Intra-Entity Transfers of Assets Other Than Inventory In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.

The Company adopted the guidance in the first quarter of fiscal 2019. The adoption of ASU No. 2016-16 did not have a material impact on the Company’s consolidated financial statements. Hedging Activities In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities which amends and simplifies existing guidance to allow companies to more accurately present the economic effects of risk management activities in the financial statements. For cash flow and net investment hedges as of the adoption date, the guidance requires a modified retrospective approach. The amended presentation and disclosure guidance is required only prospectively. The Company adopted the guidance in the first quarter of fiscal 2019. The adoption of ASU 2017-12 did not have a material impact on the Company’s consolidated financial statements. Leases In February 2016, the FASB issued ASU No. 2016-02, Leases. The updated accounting guidance requires lessees to recognize all leases on their balance sheet as a right-of-use asset and a lease liability with the exception of short-term leases. For income statement purposes, the criteria for recognition, measurement and presentation of expense is largely similar to previous guidance, but without the requirement to use bright-line tests in the determination of lease classification. The updated accounting guidance is effective for the Company as of October 1, 2019 and early adoption is permitted. In July 2018, the FASB issued ASU No. 2018-11, Leases: Targeted Improvements, which allows entities the option to adopt this standard using the modified retrospective transition method and include required disclosures for prior period. The Company is in the process of reviewing its leasing arrangements in order to determine the impact the new guidance will have on its accounting, financial statement presentation and disclosure and to compare its accounting policies and practices to the requirements of the new standard. The Company is also evaluating any system, control and process changes to capture lease data necessary to apply the new standard. The Company anticipates an increase in lease-related assets and liabilities on its consolidated balance sheets as a result of recognition of most operating leases, and anticipates adopting the standard using the modified retrospective transition method, in accordance with ASU No. 2018-11. Fair Value Measurement In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement which modifies the disclosures on fair value measurements by removing the requirement to disclose the amount and reason for transfers between Level 1 and Level 2 of the fair value hierarchy and the policy for timing of such transfers. The ASU expands the disclosure requirements for Level 3 fair value measurements, primarily focused on changes in unrealized gains and losses included in other comprehensive income. For public entities, the standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for any removed or modified disclosures and adoption of the additional disclosures can be delayed until the effective date. The Company does not currently expect the adoption of ASU 2018-13 to have a material impact on its consolidated financial statements and disclosures due to the nature and materiality of the Company’s financial assets and liabilities.
