Recently Issued Accounting Pronouncements [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 effective date. The new comprehensive revenue recognition standard will supersede 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 with a cumulative adjustment to retained earnings of approximately $10 million. The adoption of this standard will change the timing of revenue recognition for most of our transportation business from at delivery to over the transit period as our performance obligation is completed. Due to the short transit period of many of our performance obligations, we do not expect this change to have a material impact on our results of operations, financial position, or cash flows once implemented. The new standard will expand our existing revenue recognition disclosures upon adoption beginning in the first quarter of 2018. In addition, we have identified certain customer contracts in our sourcing business that will change from a principal to an agent relationship under the new standard. This will cause the revenue associated with these contracts to be recognized at the net amount we charge our customers but will have no impact on income from operations. 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 in the first quarter of 2019 using a modified retrospective approach. Early adoption is permitted, although we do not plan to adopt early. We have obligations under lease agreements for facilities and equipment, which are classified as operating leases under the existing lease standard. While we are still evaluating the impact ASU 2016-02 will have on our consolidated results of operations, financial condition, and cash flows, our financial statements will reflect an increase in both assets and liabilities due to the requirement to recognize right-of-use assets and lease liabilities on the consolidated balance sheets for our facility and equipment leases. See Note 7 to our consolidated financial statements which presents our operating lease commitments as of December 31, 2017. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718). This update was issued as part of the FASB’s simplification initiative and affects all entities that issue share-based payment awards to their employees. The amendments in this update cover such areas as the recognition of excess tax benefits and deficiencies, the classification of those excess tax benefits on the statement of cash flows, and accounting policy election for forfeitures, the amount an employer can withhold to cover income taxes and still qualify for equity classification, and the classification of those taxes paid on the statement of cash flows. This update is effective for annual and interim periods beginning after December 15, 2016. During the first quarter of 2017, we adopted ASU 2016-09, Compensation - Stock Compensation (Topic 718). The adoption of ASU 2016-09 prospectively impacts the recording of income taxes related to share-based payment awards in our consolidated statement of financial position and results of operations, as well as the operating and financing cash flows on the consolidated statements of cash flows. The magnitude of such impacts are dependent on our future grants of stock-based compensation, our future stock price in relation to the fair value of awards on grant date, and the exercise behavior of our option holders. We prospectively adopted these provisions in the first quarter of 2017. This adoption resulted in a decrease in our provision for income taxes for the year ended December 31, 2017 of $13.7 million. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and other (Topic 350). This update simplifies the accounting for goodwill impairment and removes Step 2 of the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, any impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The ASU is effective for annual and any interim impairment tests for periods beginning after December 15, 2019. Early adoption is permitted for interim and annual goodwill impairment tests performed after January 1, 2017. We early adopted this ASU for our annual impairment test performed on November 30, 2017. There was no impact resulting from this adoption on our consolidated financial statements. 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 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 2017 Tax Act. The amendment provides the option to reclassify stranded tax effects resulting from the 2017 Tax Act and 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, though early adoption is permitted. We are currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures.

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 effective date. The new comprehensive revenue recognition standard will supersede all existing revenue recognition guidance under U.S. GAAP.

The adoption of this standard will change the timing of revenue recognition for most of our transportation business from at delivery to over the transit period as our performance obligation is completed. Due to the short transit period of many of our performance obligations, we do not expect this change to have a material impact on our results of operations, financial position, or cash flows once implemented.

The new standard will expand our existing revenue recognition disclosures upon adoption beginning in the first quarter of 2018. In addition, we have identified certain customer contracts in our sourcing business that will change from a principal to an agent relationship under the new standard.

This update simplifies the accounting for goodwill impairment and removes Step 2 of the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, any impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The ASU is effective for annual and any interim impairment tests for periods beginning after December 15, 2019. Early adoption is permitted for interim and annual goodwill impairment tests performed after January 1, 2017. We early adopted this ASU for our annual impairment test performed on November 30, 2017. There was no impact resulting from this adoption on our consolidated financial statements.

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 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 2017 Tax Act. The amendment provides the option to reclassify stranded tax effects resulting from the 2017 Tax Act and 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, though early adoption is permitted. We are currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures.
