Quarterly Financial Information Disclosure [Abstract]
Interest - Imputation of Interest	We adopted ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”), which provides guidance on simplifying the presentation of debt issuance costs on the balance sheet. To simplify presentation of debt issuance costs, the amendments in ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. In accordance with ASU 2015-03, we are applying the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented was adjusted to reflect the period-specific effects of applying the new guidance.
Inventory	We adopted ASU No. 2015-11, Inventory (Topic 330) - Simplifying the Measurement of Inventory (“ASU 2015-11”), which simplifies the subsequent measurement of inventories by replacing the lower of cost or market test with a lower of cost and net realizable value test. The subsequent measurement of inventory test, historically three measurements under lower of cost or market, is replaced by lower of cost and net realizable value test. Thus, we will compare the cost of inventory to only one measure, its net realizable value. When evidence exists that the net realizable value of inventory is less than its cost (due to damage, physical deterioration, obsolescence, changes in price levels or other causes), we will recognize the difference as a loss in earning in the period in which it occurs. In accordance with ASU 2015-11, we are applying the new guidance on a prospective basis.
Business Combinations	We adopted ASU No. 2015-16, Business Combinations (Topic 805) - Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16), which eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, we will recognize a measurement-period adjustment during the period in which we determine the amount of the adjustment, including the effect on earnings of any amounts it would have recorded in previous periods if the accounting had been completed at the acquisition date. In accordance with ASU 2015-16, we are applying the new guidance on a prospective basis to adjustments to provisional amounts that occur after December 31, 2015. That is, the ASU applies to open measurement periods, regardless of the acquisition date.
Income Taxes	We adopted ASU No. 2015-17, Income Taxes (Topic 740), Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). We will classify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. In addition, we will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances also will be classified as noncurrent. We have chosen to apply ASU 2015-17 on a prospective basis. Therefore, the prior periods were not retroactively adjusted.
