Quarterly Financial Information Disclosure [Abstract]

Summary of Selected Quarterly Financial Data

The following table provides selected consolidated financial information from continuing operations on a quarterly basis for each quarter of 2017 and 2016. The Company’s business is seasonal and particularly sensitive to weather conditions. Interim amounts are therefore subject to significant fluctuations (in millions, except per share data).
