NEW ACCOUNTING STANDARDS
NEW ACCOUNTING STANDARDS	2. NEW ACCOUNTING STANDARDS New Accounting Standards Issued and Adopted In January 2017, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2017-04, Intangibles–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). The ASU simplifies the subsequent measurement of goodwill by eliminating the need for an entity to determine the implied fair value of goodwill to calculate an impairment charge. Under the new guidance an entity compares the fair value of the reporting unit containing the goodwill to its carrying value and records any excess carrying value as an impairment charge. This new standard is applied prospectively and is effective for annual and interim periods beginning after December 15, 2019; however, early adoption is permitted. We have early adopted this new standard and will apply the guidance to any future goodwill impairment assessments. In March 2016, the FASB issued ASU 2016-09, Compensation–Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"). ASU 2016-09 simplifies the accounting for several aspects of share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, flexibility in the accounting for forfeitures and classification on the statement of cash flows. ASU 2016-09 was effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted. The adoption of ASU 2016-09 did not have a material impact on our condensed consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory ("ASU 2015-11"). ASU 2015-11 simplifies the subsequent measurement of inventory. It replaces the current lower of cost or market test with the lower of cost or net realizable value test. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new standard was applied prospectively and was effective for annual reporting periods beginning after December 15, 2016 and interim periods within those annual periods, with early adoption permitted. The adoption of ASU 2015-11 did not have a material impact on our condensed consolidated financial statements. New Accounting Standards Issued and Not Yet Adopted In March 2017, the FASB issued ASU 2017-07, Compensation–Retirement Benefits (Topic 715) ("ASU 2017-07"). ASU 2017-07 requires that an employer disaggregate the service cost component from the other components of net benefit cost. It also provides explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allows only the service cost component of net benefit cost to be eligible for capitalization. The new guidance will be applied retroactively to all periods presented. ASU 2017-07 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. We are currently evaluating the effect of adopting ASU 2017-07, but do not anticipate it will have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). ASU 2016-13 changes the impairment model for most financial assets and certain other instruments to require the use of a new forward-looking "expected loss" model that generally will result in earlier recognition of allowances for losses. The new standard will require disclosure of significantly more information related to these items. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted for the fiscal year beginning after December 15, 2018, including interim periods. We are currently evaluating the effect of adopting ASU 2016-13, but do not anticipate it will have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 increases transparency and comparability among organizations by requiring lessees to record right-to-use assets and corresponding lease liabilities on the balance sheet and disclosing key information about lease arrangements. The new guidance will classify leases as either finance or operating (similar to current standard's "capital" or "operating" classification), with classification affecting the pattern of income recognition in the statement of income. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the effect of adopting ASU 2016-02. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 is a new revenue recognition standard that provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle of the new standard is as follows: An entity 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. ASU 2014-09 was originally effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date ("ASU 2015-14"), which deferred the effective date by one year while providing the option to early adopt the standard on the original effective date. The ARLP Partnership developed an assessment team to determine the effect of adopting ASU 2014-09. As part of the assessment process, the ARLP Partnership applied the five-step analysis outlined in the new standard to certain contracts representative of the majority of its coal sales contracts and determined that its pattern of recognition appears consistent between both the new and existing standards. The ARLP Partnership also reviewed the expanded disclosure requirements under the new standard and determined the additional information to be disclosed. In addition the ARLP Partnership reviewed its business processes, systems and internal controls over financial reporting to support the new recognition and disclosure requirements under the new standard. Based on the results of the ARLP Partnership's assessment team, the ARLP Partnership has started its implementation of the new standard. The ARLP Partnership continues to report its implementation progress for the new standard to its management and MGP's audit committee. The ARLP Partnership continues to monitor closely a) activities of the FASB and various non-authoritative groups with respect to implementation issues that might impact its determinations, b) existing contracts for consistency with current implementation determinations derived from it assessment process and c) its revenue recognition policy, where applicable, for required modifications. We do not expect that the adoption of the new standard will have a material impact on our financial statements, but will require expanded disclosures including presenting, by type and by segment, revenues for all periods presented and expected revenues by year for performance obligations that are unsatisfied or partially unsatisfied as of the date of presentation. The new standard allows for two methods of adoption: a full retrospective adoption method and a modified retrospective method. We have elected to use the modified retrospective method of adoption which allows a cumulative effect adjustment to equity as of the date of adoption.
