Accounting Changes and Error Corrections [Abstract]
Accounting Changes	Accounting Changes In July 2015, the FASB amended its guidance related to the measurement of inventory. The amended guidance requires inventory to be measured at the lower of cost and net realizable value and thereby simplifies the current guidance of measuring inventory at the lower of cost or market. The amended guidance is effective prospectively for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The Company adopted the guidance during the first quarter of 2017 and it did not have a material impact on its Consolidated Financial Statements. In March 2016, the FASB amended its guidance related to the accounting for certain aspects of share-based payments to employees. The amended guidance requires that all tax effects related to share-based payments are recorded at settlement (or expiration) through the income statement, rather than through equity. Cash flows related to excess tax benefits are no longer separately classified as a financing activity apart from other income tax cash flows. The amended guidance also allows for an employer to repurchase additional employee shares for tax withholding purposes without requiring liability accounting and clarifies that all cash payments made to tax authorities on an employee’s behalf for withheld shares should be presented as a financing activity on the Consolidated Statements of Cash Flows. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted, and the Company elected to early adopt in the third quarter of 2016. The adoption in the third quarter of 2016 required the Company to reflect any adjustments as of January 1, 2016, the beginning of the annual period that includes the interim period of adoption. We determined that the most significant impact of adoption was the recognition of excess tax benefits in our provision for income taxes rather than through equity for all periods, through the period of adoption. The adoption resulted in the recognition of excess tax benefits in our provision for income taxes of $44 related to the three-month period ended March 31, 2016 and $125 in the three-month period ended March 31, 2017. The presentation requirements for cash flows related to excess tax benefits and employee taxes paid for withheld shares were applied retrospectively to all periods presented. This resulted in an increase in both net cash provided by operating activities and net cash used by financing activities of $413 for the three month period ended March 31, 2016.
