Commitments and Contingencies

At December 31, 2013, we were obligated under various operating lease agreements. Rental expense in 2013 was $10.3 million. Net rental expense in 2012 and 2011 was $12.0 million and $11.4 million, respectively, and is net of sublease income of $0.4 million and $0.8 million, respectively.

At December 31, 2013, future minimum rental payments under non-cancelable operating leases were:

Year	($ in millions)
2014	$	10.5
2015	9.0
2016	7.4
2017	5.1
2018	4.1
Thereafter	17.4
Total	$	53.5

At December 31, 2013, outstanding unconditional contractual commitments for the purchase of raw materials and equipment amounted to $31.9 million, of which $17.9 million is due to be paid in 2014.

We have letters of credit totaling $3.5 million supporting the reimbursement of workers' compensation and other claims paid on our behalf by insurance carriers. Our accrual for insurance obligations was $8.5 million at December 31, 2013, of which $4.7 million is in excess of our deductible and, therefore, is reimbursable by the insurance company.

Our SmartDose contingent consideration is payable to the selling shareholders based upon a percentage of product sales over the life of the underlying product patent, which is 17 years, with no cap on total payments. Given the length of the earnout period and the uncertainty in forecasted product sales, we do not believe it is meaningful to estimate the upper end of the range over the entire period. However, our estimated probable range which could become payable over the next five years is between zero and $4.2 million.

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, 2013 related to these matters and adjusted for expected amnesty benefits was $3.0 million.
