Commitments and Contingencies
 
At September 30, 2015, the Company had $8.0 million in letters of credit outstanding as guarantees of contract performance. At September 30, 2015, the Company had $6.3 million of outstanding firm purchase obligations to purchase goods and services. As a normal incident of the businesses in which the Company is engaged, various claims, charges and litigation are asserted or commenced from time to time against the Company. Additionally, the Company is currently involved in various stages of investigation and remediation relating to environmental matters. It is the opinion of Management that the aggregate costs involved in the resolution of these matters, and final judgments, if any, which might be rendered against the Company are adequately reserved for, are covered by insurance, or are not likely to have a material adverse effect on the Company’s results from continuing operations, capital expenditures, or competitive position.
