Commitments and Contingencies Disclosure [Abstract] |
Contingencies And Guarantees Disclosure | COMMITMENTS AND CONTINGENCIES Product Warranties The company provides warranty coverage to the end-user for parts and labor on products sold. The standard length of warranty is twelve years for the majority of products sold; however, this varies depending on the product classification. The company does not sell or otherwise issue warranties or warranty extensions as stand-alone products. Reserves have been established for the various costs associated with the company's warranty program and are included in the Condensed Consolidated Balance Sheets under “Accrued warranty.” General warranty reserves are based on historical claims experience and other currently available information. These reserves are adjusted once an issue is identified and the actual cost of correction becomes known or can be estimated.

Guarantees The company is periodically required to provide performance bonds in order to do business with certain customers. These arrangements are common and generally have terms ranging between one and three years. The bonds are required to provide assurance to customers that the products and services they have purchased will be installed and/or provided properly and without damage to their facilities. The bonds are provided by various bonding agencies; however, the company is ultimately liable for claims that may occur against them. As of February 28, 2015, the company had a maximum financial exposure related to performance bonds totaling approximately $9.1 million. The company has no history of claims, nor is it aware of circumstances that would require it to pay, under any of these arrangements. The company also believes that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially affect the company's financial statements. Accordingly, no liability has been recorded in respect to these bonds as of February 28, 2015 and May 31, 2014. The company has entered into standby letter of credit arrangements for purposes of protecting various insurance companies and lessors against default on insurance premium and lease payments. As of February 28, 2015, the company had a maximum financial exposure from these standby letters of credit totaling approximately $8.3 million, all of which is considered usage against the company's revolving credit facility. The company has no history of claims, nor is it aware of circumstances that would require it to perform under any of these arrangements, and believes that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially affect the company's financial statements. Accordingly, no liability has been recorded in respect of these arrangements as of February 28, 2015 and May 31, 2014. Contingencies The company leases a facility in the United Kingdom under an agreement that expired in June 2011, and the company is currently leasing the facility on a month-to-month basis. Under the terms of the lease, the company is required to perform the maintenance and repairs necessary to address the general dilapidation of the facility. The ultimate cost of this provision to the company is dependent on a number of factors including, but not limited to, the future use of the facility by the lessor and whether the company chooses and is permitted to renew the lease term. The company has estimated the cost of these maintenance and repairs to be between $0 million and $3.0 million, depending on the outcome of future plans and negotiations. As a result, an estimated liability of $1.2 million and $1.5 million was recorded under the caption “Other accrued liabilities” in the Condensed Consolidated Balance Sheets as of February 28, 2015, and May 31, 2014, respectively. The company is also involved in legal proceedings and litigation arising in the ordinary course of business. In the opinion of management, the outcome of such proceedings and litigation currently pending will not materially affect the company's consolidated financial statements.
