Restructuring and Related Activities [Abstract]
Restructuring Expense	RESTRUCTURING EXPENSE During 2017 and 2016, in response to declining product prices, we undertook several cost saving actions that were intended to better align our cost structure with the business environment. These initiatives included workforce reductions, bonus plan curtailments, and temporary salary decreases for most employees. For the years ended December 31, 2017, and 2016 we recorded restructuring expense of $0.3 million and $2.7 million, respectively, related to these initiatives. For the year ended December 31, 2018, we recorded no restructuring expenses.
