New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, and in August 2015, issued ASU 2015-14, which amended the standard as to its effective date. The new comprehensive revenue recognition standard supersedes all existing revenue recognition guidance under U.S. GAAP. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to a customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. We adopted this new standard effective January 1, 2018, under the modified retrospective transition method applied to contracts that were not completed as of the date of initial application resulting in a $9.2 million cumulative adjustment to retained earnings. We have updated our revenue recognition critical accounting policy due to the adoption of this standard and expanded the summary of significant accounting policies included in Note 1, Summary of Significant Accounting Policies, as a result of the adoption. The adoption of this standard changed the timing of revenue recognition for our transportation businesses from at delivery to over the transit period as our performance obligations are completed. Due to the short transit period of many of our performance obligations, this change did not have a material impact on our results of operations or cash flows. The new standard expanded our existing revenue recognition disclosures upon adoption. In addition, we have identified certain customer contracts in our sourcing business that changed from a principal to an agent relationship under the new standard. This change resulted in these contracts being recognized at the net amount we charge our customers but had no impact on income from operations. The expanded disclosures required by ASU 2014-09 have been included in Note 10, Revenue Recognition. In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. This update amends the scope of modification accounting for share-based payment arrangements. The ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under Topic 718. We adopted this new standard effective January 1, 2018. The amendments in this update will be applied prospectively to awards modified on or after January 1, 2018. The future impact of ASU 2017-09 will depend on the nature of future stock award modifications. In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40). This update aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. We adopted this new standard in 2018, using a prospective approach. The adoption did not have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This update requires a lessee to recognize on the balance sheet a liability to make lease payments and a corresponding right-of-use asset. The guidance also requires certain qualitative and quantitative disclosures about the amount, timing, and uncertainty of cash flows arising from leases. This update is effective for annual and interim periods beginning after December 15, 2018, which will require us to adopt these provisions on January 1, 2019. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides another transition method no longer requiring application to previously reported periods. Therefore, prior period balances will not be restated. We have taken the necessary steps to be compliant as well as designed the necessary internal controls to facilitate the adoption of the new standard. We have obligations under lease agreements for facilities and equipment, which are classified as operating leases under both the existing and new lease standard. We have adopted Topic 842 effective January 1, 2019, by recognizing right-of-use assets and lease liabilities of approximately $265.4 million and $273.3 million, respectively. The adoption of this standard is not expected to have a significant impact on our consolidated results of operations. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income, which amends existing guidance for reporting comprehensive income to reflect changes resulting from the Tax Cuts and Jobs Act of 2017 ("Tax Act"). The amendment provides the option to reclassify stranded tax effects resulting from the Tax Act within accumulated other comprehensive income (AOCI) to retained earnings. New disclosures will be required upon adoption, including the accounting policy for releasing income tax effects from AOCI, whether reclassification of stranded income tax effects is elected, and information about other income tax effect reclassifications. The amendment will become effective for us on January 1, 2019. We do not expect this standard to have a material impact on our consolidated financial statements and disclosures.
