Based on the effective dates, we expect to adopt the new guidance in the first quarter of Fiscal 2020 using the modified retrospective basis as of the beginning of the period of adoption. We have established an implementation plan and have made progress on this plan including surveying our businesses, assessing our lease population, and compiling information on our active leases. In addition, we are determining needed changes to our policies, business processes, internal controls, and disclosures. Based on our analysis, we do not expect a material impact to our consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815), which improves the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. ASU 2017-12 is effective for annual reporting periods beginning after December 15, 2018 (our Fiscal 2020), including interim periods within those annual reporting periods. Early adoption is permitted. We expect to adopt the new guidance in the first quarter of Fiscal 2020, and we do not expect a material impact to our consolidated financial statements. Recently Adopted Accounting Pronouncements In the first quarter of Fiscal 2019, we adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which establishes a comprehensive five-step model for the recognition of revenue from contracts with customers. This model is based on the core principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We elected the modified retrospective method of adoption, which we applied to contracts not completed as of the initial date of adoption. Application of the transition requirements had no material impact on operations or beginning retained earnings. While certain control processes and procedures were updated for this adoption, the changes did not have a material impact on our internal control over financial reporting framework. Also in the first quarter of Fiscal 2019, we retrospectively adopted ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (Topic 230), which provides guidance for eight specific cash flow issues with the objective of reducing the existing diversity in practice. The adoption of this standard did not materially impact our statements of cash flows, and no cash flow reclassifications were required for the prior period.
