Recently Issued Accounting Standards

Revenue Recognition
In May 2014, the FASB issued the “Revenue from Contracts with Customers” accounting standard, which supersedes the revenue recognition requirements in the “Revenue Recognition” accounting standard and most industry-specific guidance. This amendment is based on the principle that revenue is recognized to depict the transfer of 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. It also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Additionally, the new standard requires the deferral of direct incremental selling costs to the period in which the underlying revenue is recognized. The amendments will be applied using one of two retrospective methods. The new guidance is effective for us beginning January 1, 2017 and we are still evaluating the impact of adoption on our consolidated results of operations.
Consolidation
In February 2015, the FASB amended the "Consolidation" accounting standard to revise the consolidation model for limited partnerships, variable interest entities, and certain investment funds. Further, the amendment provides guidance on how fee arrangements and related parties should be considered when determining whether to consolidate variable interest entities. As a result of this amendment, all legal entities are required to be reevaluated to determine if they should be consolidated. The new guidance is effective for us on January 1, 2016 and we are still evaluating the impact of adoption on our consolidated results of operations, consolidated financial position, and cash flows.
Debt Issuance Costs
In April 2015, the FASB amended the "Interest-Imputation of Interest" accounting standard to simplify the presentation of debt issuance costs on the balance sheet. Currently, debt issuance costs are included in Other current assets and Deferred charges and other assets on our consolidated balance sheet. The amendment requires that these costs instead be presented as a direct deduction from the carrying amount of Current maturities of long-term debt and Long-term debt, consistent with the presentation of debt discounts. This change does not impact the manner in which the debt issuance costs are expensed over the life of the debt. The change in presentation is effective for us on January 1, 2016. As of March 31, 2015, the effect of this amendment would have been to reduce Other current assets and Current maturities of long-term debt by $9.3 million and to reduce Deferred charges and other assets and Long-term debt by $37.4 million. As of December 31, 2014 the effect of this amendment would have been to reduce Other current assets and Current maturities of long-term debt by $9.2 million and to reduce Deferred charges and other assets and Long-term debt by $39.7 million.
Cloud Computing Arrangements
In April 2015, the FASB amended the "Intangibles—Goodwill and Other—Internal-Use Software" accounting standard to provide guidance on whether a cloud computing arrangement contains a software license. If a cloud computing arrangement includes a software license, then we should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, we should account for the arrangement as a service contract. The new guidance is effective for us on January 1, 2016 and we are still evaluating the impact of adoption on our consolidated results of operations, consolidated financial position, and cash flows.
