The Company, through its manufacturers, provides parts warranties for products sold. These warranties are mainly the responsibility of the manufacturer. As such, warranty-related expenses are generally insignificant to the Company’s consolidated financial statements.  

Further, in the ordinary course of business, certain of the Company’s contracts require the Company to provide performance and payment bonds related to projects in process. These bonds are intended to provide a guarantee to the customer that the Company will perform under the terms of the contract and that the Company will pay subcontractors and vendors. If the Company fails to perform under the contract or pay subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. The Company is required to reimburse the surety for any such expenses or outlays it incurs. As of June 30, 2019 and June 30, 2018, outstanding performance and payment bonds totaled $8.0 million and $8.3 million, respectively. As of June 30, 2019, there were no estimated costs to complete on projects secured by these bonds. As of June 30, 2018, estimated costs to complete projects secured by these bonds totaled $4.4 million.  

The Company may from time to time become subject to litigation and other legal proceedings. Litigation and other legal proceedings may require the Company to incur significant expenses, including those relating to legal and other professional fees. In addition, litigation and other legal proceedings are inherently uncertain, and adverse outcomes in litigation or other legal proceedings could adversely affect the Company’s financial condition, cash flows, and operating results.
