Commitments and Contingencies

Lease Commitments

Total rental expense for the years ended December 31, 2018 and 2017 amounted to $3.3 million and $2.6 million, respectively. Of the $10.8 million future minimum operating lease commitments outstanding at December 31, 2018, $4.0 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 June 2019 and includes total future minimum lease proceeds of less than $0.1 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 $5.1 million.

The Company’s future minimum lease commitments, principally for facilities and equipment, as of December 31, 2018, were as follows:

At December 31, 2018, the cost and accumulated depreciation of the asset related to the financing lease were $13.0 million and $8.5 million, respectively, and the cost and accumulated amortization of the assets related to capital leases were $0.7 million and $0.3 million, respectively. The Company will adopt ASU 2016-02 on January 1, 2019. See Note 4 - Leases for a further description.

In the first quarter of 2012, the Company signed a 10 year agreement to lease space for a new corporate headquarters in Chicago, Illinois ("Lease"). In the fourth quarter of 2013, due to excess capacity as a result of a corporate restructuring, the Company agreed to sublease a portion (approximately 17,100 square feet) of its corporate headquarters to a third party ("Sublease"). Both the Lease and the Sublease were scheduled to terminate in the first quarter of 2023.

In 2018, the Company entered into agreements with the lessor and the sub-lessee to terminate both the Lease and Sublease in June 2019. The original loss recorded on the Sublease was reduced by $0.7 million in the second quarter of 2018 to reflect the shortened lease time frame. Additionally, the Company is required to pay a $0.5 million cancellation fee before June 2019 as a condition of early termination of the original Lease. As a result of these transactions, a $0.2 million net gain was recognized in 2018. The $0.5 million early termination fee is included in current liabilities in the condensed consolidated balance sheet. The termination of the Lease reduced the Company’s future operating lease obligation by $1.2 million, offset by a reduction in future payments from the Sublease of $0.4 million. The accounting for the lease termination will not be impacted by the adoption of ASU 2016-09.

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, results of operations or cash flows.

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 retained an environmental consulting firm to further investigate the contamination including the measurement and monitoring of the site and the site was enrolled in the Alabama Department of Environmental Management (“ADEM") voluntary cleanup program.

In 2017 the Company received estimates from its environmental consulting firm for two remediation solutions based on a chemical injection process. The first solution would consist of chemical injections throughout the entire site to directly eliminate the hazardous substances in the soil and groundwater. The second solution would consist of chemical injections around the perimeter of the site to prevent the migration of the hazardous chemicals off-site. Neither solution would require additional excavation or repairs to be made to the property. Additionally, the estimated required monitoring period would be substantially reduced. The estimated expenditures over an 18 month period under the two injection scenarios ranged from $0.9 million to $2.0 million.

In 2018, the Company received updated environmental remediation estimates from its environmental consulting firm based on information analyzed from further data collection and consultation with ADEM on their anticipated requirements. The updated remediation plan expands the chemical injection process over a larger area than previously estimated, including under the building on the property. The updated plan also requires three consecutive measurement periods of monitoring the affected area after the injection process is completed. Based upon feedback received from ADEM, the Company accrued an additional $0.5 million of expense in 2018 to bring the total liability to $1.4 million which represents the Company's best estimate of the most likely outcome. The plan was approved by ADEM in the fourth quarter of 2018 and work commenced in the first quarter of 2019. The Company believes the environmental remediation liability of $1.4 million classified as Accrued expenses and other liabilities on the accompanying Consolidated Balance Sheet will be sufficient to cover the cost of the plan. The Company does not expect to capitalize any amounts related to the remediation plan.
