Earnings Per Share

A portion of the Company's non-vested share-based payment awards are considered participating securities and as such, the Company is required to use the two-class method for the computation of basic and diluted earnings per share. Under the two-class computation method, net losses are not allocated to participating securities unless the holder of the security has a contractual obligation to share in the losses. The non-vested share-based payment awards are not allocated losses as the awards do not have a contractual obligation to share in losses of the Company.

The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations for the three months ended March 31, 2018 and 2017:
