The amended guidance outlines a single comprehensive revenue model for entities to use in accounting for revenue from contracts with customers. The guidance (including subsequent amendments) supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that "an entity recognizes 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." The ASU may be adopted using a full retrospective approach or reporting the cumulative effect as of the date of adoption. This guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years with earlier adoption permitted for fiscal years beginning after December 15, 2016. We are currently evaluating the impact of adopting this guidance. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amended guidance is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The adoption of this guidance is expected to result in a significant portion of our operating leases, where we are the lessee, to be recognized on our Consolidated Balance Sheets. The guidance requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years with earlier adoption permitted. We are currently evaluating the impact and timing of adopting this guidance. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amended guidance is intended to simplify several aspects of accounting for share-based payment award transactions, including income tax consequences, accounting for forfeitures, and classification of awards as either equity or liabilities and classification in the statement of cash flows. ASU 2016-09 has separate transition guidance for each element of the new standard and is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years with earlier adoption permitted. We are currently evaluating the impact of adopting this guidance. We do not expect that any other recently issued accounting guidance will have a significant effect on our financial statements.
