New Accounting Pronouncements Not Yet Adopted | New Accounting Pronouncements Not Yet Adopted ﻿ In May 2014, the FASB issued Accounting Standard Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606), which will replace most of the existing revenue recognition guidance within U.S. GAAP. The FASB has also issued several updates to ASU 2014-09. The core principle of ASU 2014-09 is that an entity should recognize revenue for the transfer of goods or services to customers in an amount that it expects to be entitled to receive for those goods or services. In doing so, companies will be required to make certain judgments and estimates, including identifying contract performance obligations, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price among separate performance obligations. Additionally, disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, significant judgments reached in the application of the guidance and assets recognized from the costs to obtain or fulfill a contr act will be required. In July 2015, the FASB approved a one-year deferral of the effective date to all annual and interim periods beginning after December 15, 2017. The new guidance permits two methods of adoption: a full retrospective method to each prior reporting period presented or a modified retrospective approach with the cumulative effect of initially applying the guidance recognized at the date of initial application. We are continuing to evaluate the impact of this new standard. While ASU 2014-09 will not impact the overall economics of our products and services sold under customer incentive programs, we do expect the new standard will require us to delay revenue recognition related to certain of our customer ince ntive programs and to accelerate revenue recognition for certain other customer incentive programs. The volume and mix of future customer incentive programs will affect our assessment of the overall net impact of the new standard on our results and will also influence our choice of adoption method. We plan to determine our method of adoption and provide an estimate of any impacts by October 2017, in connection with our financial reporting for the quarter ending September 30, 2017. ﻿ In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations’ leasing arrangements. The principal difference from previous guidance is that effective upon adoption, the lease assets and lease liabilities arising from operating leases will be recognized in the balance sheet. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. In transition, we are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach, including the option to utilize a number of practical expedients. We are in process of evaluating our lessee and lessor arrangements to determine the impact of this amendment on the consolidated financial statements. This evaluation includes an extensive review of revenue through leasing arrangements as well as lease expenses, which are primarily through operating lease arrangements for most of our facilities. ﻿ In February 2017, the FASB issued ASU 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets. The ASU clarifies the scope and accounting of a financial asset that meets the definition of an “in-substance nonfinancial asset” and defines the term, “in-substance nonfinancial asset.” The ASU also adds guidance for parti al sales of nonfinancial assets. The new guidance is effective for fiscal years beginning after December 15, 2017 and interim periods within those years. Early adoption is permitted for interim or annual reporting periods beginning after December 15, 2016. The guidance may be applied retrospectively for all periods presented or retrospectively with a cumulative-effect adjustment at the date of adoption. The Company is currently evaluating the effects of ASU 2017-05 on its consolidated financial statements
