The guidance will require prospective application at the beginning of our first quarter of fiscal 2018, but permits adoption in an earlier period. We are currently evaluating the effect that adopting ASU 2015-11 will have on our consolidated results of operations, cash flows, and financial position. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which was issued as a new topic, Accounting Standards Codification ("ASC") 606. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle of the guidance is that a company should recognize revenue 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. This standard will also result in enhanced disclosures about revenue, providing guidance for transactions that were not previously addressed comprehensively and improving guidance for multiple-element arrangements. The FASB recently announced plans to defer the effective adoption date for one year. ASU 2014-09 is effective for us beginning in fiscal 2019 and can be adopted by the Company either retrospectively or as a cumulative-effect adjustment as of the date of adoption. We are currently evaluating the effect that adopting ASU 2014-09 will have on our consolidated results of operations, cash flows, and financial position.
