| Subsequent Events | Note 15: Subsequent Events On July 5, 2018, the Company entered into an agreement for the sale of the majority of its Contract Operations Group to subsidiaries of Veolia Environnement S.A. for $27 million. The sale agreement includes the transfer of 23 of the Contract Operations Group’s 33 O&M contracts. The Company closed on the sale of 17 of the 23 contracts on July 13, 2018, and expects to close on the remaining contracts, subject to customer consents, by the end of 2018. On July 31, 2018, a new, five-year national benefits health and welfare agreement was ratified, covering approximately 3,200 of the Company’s union-represented employees, which includes 17 labor unions and 69 collective bargaining agreements. Most of the benefits under this new agreement will become effective on January 1, 2019, and include, among other things, union-represented employees’ participation in the Company’s cash-based annual performance plan, additional medical plan options and changes to certain retiree medical benefits which will require the Company to re-measure its other postretirement benefit plan obligation during the third quarter of 2018. |
