Commitments and Contingencies

Lease Commitments

Total rental expense for the years ended December 31, 2014, 2013 and 2012 amounted to $1.8 million, $2.2 million and $2.5 million, respectively. Of the $15.8 million future minimum operating lease commitments outstanding at December 31, 2014, $9.6 million relates to a lease for the Company's headquarters which expires in March 2023. The lease commitment is partially offset by a portion of the headquarters that has been sub-leased through March 2023 and includes total future minimum lease proceeds of $0.8 million.

The Company has a financing lease for the McCook Facility which expires in June 2022 and includes future minimum lease payments, related to the building, of $10.0 million. A non-cash increase in assets and liabilities of $8.0 million in 2012 related to the construction of the McCook Facility was not reflected in the Consolidated Statements of Cash Flows as it represented a non-cash investing and financing activity.

The Company’s future minimum lease commitments, principally for facilities and equipment, as of December 31, 2014, were as follows:

At December 31, 2014, the cost and accumulated depreciation of the asset related to the financing lease were $13.0 million and $3.3 million, respectively, and the cost and accumulated amortization of the assets related to capital leases were $0.3 million and $0.2 million, respectively.

Litigation, regulatory and tax matters

The Company is involved in legal actions that arise in the ordinary course of business. It is the opinion of management that the resolution of any currently pending litigation will not have a material adverse effect on the Company’s financial position or results of operations.

Environmental matter

In 2012, the Company identified that a site it owns in Decatur, Alabama contains hazardous substances in the soil and groundwater as a result of historical operations prior to the Company's ownership. The Company has retained an environmental consulting firm to further investigate the contamination including the measurement and monitoring of the site. In August 2013, the site was enrolled in Alabama's voluntary cleanup program. On October 30, 2014, the Company received estimates from its environmental consulting firm with three potential remediation solutions. The estimates include a range of viable remedial approaches, but agreement with Alabama’s voluntary cleanup program has not yet been reached. The first solution includes limited excavation and removal of the contaminated soil along with monitoring for a period up to 10 years. The second solution includes the first solution plus the installation of a groundwater extraction system. The third scenario includes the first and second solutions plus treatment injections to reduce the degradation time. The estimated expenditures over a 10-year period under the three scenarios range from $0.3 million to $1.4 million, of which up to $0.3 million may be capitalized. As the Company has determined that a loss is probable; however, no scenario is more likely than the other at this time, a liability in the amount of $0.3 million has been established and included in other long-term liabilities in the accompanying 2014 Consolidated Balance Sheet.

Tax matter

The Company was subject to an examination by the Canada Revenue Authority ("CRA") for the years 2006 through 2010. The CRA examination was completed during May 2013 and resulted in proposed adjustments which amount to $1.3 million of additional tax for the 2008 and 2009 tax years. The Company is not in agreement with these adjustments and filed a request with Competent Authority programs in both the U.S. and Canada in October, 2013. The Competent Authority program assists taxpayers with respect to matters covered in the mutual agreement procedure provisions of tax treaties. Management has not recorded a reserve and is confident that the Company will prevail in this matter. The Company is unable to establish an estimated time frame in which this issue will be resolved through Competent Authority.
