Restructuring and Related Activities [Abstract]
Restructuring and Asset Impairment Charges	Restructuring and Asset Impairment Charges Restructuring and asset impairment charges for the three and nine months ended March 31, 2016 were $17.6 million and $18.0 million, respectively. The restructuring and asset impairment charges consisted primarily of an early retirement incentive funded by the Company's qualified pension plan of $9.4 million and non-cash impairment charges on certain long-lived assets of $7.6 million due to the prolonged weakness in oil and gas drilling and exploration activities and the impact this weakness had on certain reporting units.
