Quarterly Financial Information Disclosure [Abstract]

Schedule of Selected Quarterly Financial Data

Provided below are selected unaudited quarterly financial data for 2017 and 2016.

The earnings per share information is calculated independently for each quarter based on the weighted average number of common stock and common stock equivalents outstanding, which may fluctuate, based on quarterly income levels and market prices. Therefore and due to the seasonality of the Company’s earnings, the sum of the quarters’ per share information may not equal the annual amount presented on the Consolidated Statements of Operations.
