Commitments and Contingencies

At December 31, 2012, we were obligated under various operating lease agreements with terms ranging from one month to 35 years. Net rental expense in 2012, 2011 and 2010 was $12.0 million, $11.4 million and $10.2 million, respectively, and is net of sublease income of $0.4 million, $0.8 million and $0.7 million, respectively.

At December 31, 2012, future minimum rental payments under non-cancelable operating leases were:

Year	($ in millions)
2013	$	9.1
2014	8.4
2015	7.1
2016	5.6
2017	4.4
Thereafter	18.5
Total	$	53.1

At December 31, 2012, outstanding unconditional contractual commitments for the purchase of raw materials, utilities and equipment amounted to $24.5 million, of which $16.7 million is due to be paid in 2013.

We have letters of credit totaling $3.6 million supporting the reimbursement of workers' compensation and other claims paid on our behalf by insurance carriers. Our accrual for insurance obligations was $9.5 million at December 31, 2012, of which $5.6 million is in excess of our deductible and, therefore, is reimbursable by the insurance company.

During 2009, we enrolled in a tax amnesty program offered by the Brazilian government which provided for reduced penalties and interest on certain of our tax obligations. This matter is currently awaiting final disposition in the Brazilian court system. Our total accrual at December 31, 2012 related to these matters and adjusted for expected amnesty benefits was $4.1 million.
