Note 13 – Commitments and Contingencies
Leases. Operating leases consist primarily of leases for real property and equipment. The leases frequently include renewal options, escalation clauses, and require the Company to pay certain occupancy expenses. Lease expense was approximately $0.9 million for the three months ended March 31, 2017.
Capital leases consist primarily of leases for vehicles (see Note 8 – Debt). The leases are collateralized by the vehicles and require monthly payments of principal and interest. All leases transfer title at lease end for a nominal cash buyout.
Legal. The Company is continually engaged in administrative proceedings, arbitrations, and litigation with owners, general contractors, suppliers, and other unrelated parties, all arising in the ordinary courses of business. In the opinion of the Company's management, the results of these actions will not have a material adverse effect on the financial position, results of operations, or cash flows of the Company.
Energy Contracts. The Company enters into contracts with certain state agencies in Ohio to acquire, construct, implement, and install energy conservation measures, as described in the contracts. The contracts include guarantees related to yearly energy costs savings by these customers, typically over a ten-year period. To the extent the yearly savings guarantees are unmet, the Company would be required to pay the customer the difference between the amount of energy costs savings guarantee and actual savings realized. The total of those guarantee amounts for each of the years ending December 31, 2017 and 2018 are $0.3 million and $0.2 million, respectively.
Under the terms of these energy contracts, the Company provides a guarantee bond to its customers in the amount of the guaranteed savings. The Company also maintains a Service Maintenance Agreement on most of the contracts so it can ensure proper maintenance of the equipment. On contracts without a Service Maintenance Agreement, the Company has no obligation for the guarantee if the equipment is not properly maintained. From the inception of these contracts in 1997 through March 31, 2017, the Company has not been required to make any material payments for unmet energy savings under any of the contracts.
As a result of the guarantee bonds and its experience with these arrangements, the Company does not expect to incur any material liabilities with respect to the contracts. Accordingly, no liability has been recorded for the contract guarantees.
Surety. The terms of our construction contracts frequently require that we obtain from surety companies, and provide to our customers, payment and performance bonds (“Surety Bonds”) as a condition to the award of such contracts. The Surety Bonds secure our payment and performance obligations under such contracts, and we have agreed to indemnify the surety companies for amounts, if any, paid by them in respect of Surety Bonds issued on our behalf. In addition, at the request of labor unions representing certain of our employees, Surety Bonds are sometimes provided to secure obligations for wages and benefits payable to or for such employees. Public sector contracts require Surety Bonds more frequently than private sector contracts, and accordingly, our bonding requirements typically increase as the amount of public sector work increases. As of March 31, 2017, we had approximately $123.1 million in surety bonds outstanding. The Surety Bonds are issued by surety companies in return for premiums, which vary depending on the size and type of bond. 
Collective Bargaining Agreements. Many of the Company’s craft labor employees are covered by collective bargaining agreements. The agreements require the Company to pay specified wages, provide certain benefits and contribute certain amounts to multi-employer pension plans. If the Company withdraws from any of the multi-employer pension plans or if the plans were to otherwise become underfunded, the Company could incur additional liabilities related to these plans. Although the Company has been informed that some of the multi-employer pension plans to which it contributes have been classified as “critical” status, the Company is not currently aware of any significant liabilities related to this issue.
