Environmental remediation matter

In 2015 and 2014, the Company accrued $0.9 million and $0.3 million, respectively, related to estimated future remediation of an environmental matter involving land owned in Decatur, Alabama, that was part of a division that was previously sold in 2014. Refer to "Environmental Matter" in Note 11 for further details.

Impairment loss

In 2014, the Company completed the sale of its Reno, Nevada, distribution center. As part of the review of the impact of a sale, the Company determined that the full carrying amount of the asset was not recoverable. Therefore, the Company recorded a $3.0 million non-cash impairment charge prior to the sale. The Company entered into an agreement to leaseback approximately one-half of the building for a 10-year term.
 
Loss on sub-lease transaction

In 2013, the Company entered into an agreement to sub-lease a portion of its leased headquarters. Under lease accounting rules, the Company recorded a $2.9 million charge, primarily representing the net difference between the Company's future scheduled lease payments and the expected proceeds from the sub-lease, as well as related asset write downs.

Employment tax matter

In 2013, the Company recorded a reduction in other operating expenses of $0.4 million as an employment tax matter with the IRS was settled for $0.8 million. The Company originally established a $1.2 million liability in 2011 as its best estimate of the cost of settling this employment tax matter that related to the classification of the sales representatives of one of the Company’s subsidiaries.
