Facility Idling

In the fourth quarter of 2015, we temporarily idled the Ashland Works blast furnace and steelmaking operations (“Ashland Works Hot End”). We incurred charges during the fourth quarter of 2015 for supplemental unemployment and other employee benefit costs and for equipment idling, asset preservation and other costs. The supplemental unemployment and other employee benefit costs were recorded as accrued liabilities in the consolidated balance sheet, and the activity for the nine months ended September 30, 2016 was as follows:



Balance at December 31, 2015	$	22.1
Payments	(15.3		)
Balance at September 30, 2016	$	6.8

We estimate we will incur on-going costs of less than $2.0 per month for maintenance of the equipment, utilities and supplier obligations related to the temporarily idled Ashland Works Hot End. These costs were $4.7 and $17.4 for the three and nine months ended September 30, 2016. The carrying value of the long-lived assets associated with the temporarily idled operations totaled approximately $70.0 as of September 30, 2016.
