Accounting Policies [Abstract] |
Reclassifications to Previously Reported Amounts | Our financial statements for the three and nine months ended September 30, 2017 have been revised to decrease “cost of revenues, services” and increase “cost of revenues, products” by the following immaterial amounts in order to correct a misclassification associated with Blackhawk product costs. While the revisions do impact two financial statement line items, the revisions had no impact on our net income (loss), working capital, cash flows or total equity previously reported (in thousands):
