Environmental Remediation Obligations [Abstract]

ENVIRONMENTAL

NOTE 9. ENVIRONMENTAL

We are party to various government and private environmental actions associated with past manufacturing facilities and former waste disposal sites. Environmental provisions charged to income, which are included in costs of goods sold, were as follows:

	Three Months Ended March 31,
	2022		2021
	($ in millions)
Provisions charged to income	$	5.6	$	2.5
Recoveries for costs incurred and expensed	—		(2.2)
Environmental expense	$	5.6	$	0.3

Environmental expense for the three months ended March 31, 2021 includes $2.2 million of insurance recoveries for environmental costs incurred and expensed in prior periods. The condensed balance sheets included reserves for future environmental expenditures to investigate and remediate known sites amounting to $149.5 million, $147.3 million and $147.2 million at March 31, 2022, December 31, 2021 and March 31, 2021, respectively, of which $124.5 million, $122.3 million and $128.2 million, respectively, were classified as other noncurrent liabilities.

Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, developments at sites resulting from investigatory studies, advances in technology, changes in environmental laws and regulations and their application, changes in regulatory authorities, the scarcity of reliable data pertaining to identified sites, the difficulty in assessing the involvement and financial capability of other Potentially Responsible Parties (PRPs), our ability to obtain contributions from other parties and the lengthy time periods over which site remediation occurs. It is possible that some of these matters (the outcomes of which are subject to various uncertainties) may be resolved unfavorably to us, which could materially adversely affect our financial position or results of operations.
