Earnings Per Share

We have shares of restricted stock issued and outstanding that are currently unvested. Shares of restricted stock are considered participating securities because holders of shares of unvested restricted stock are entitled to the same liquidation and dividend rights as the holders of our unrestricted common stock. We are required to compute earnings per share (“EPS”) under the two-class method in periods in which we have earnings. Under the two-class method, the undistributed earnings for each period are allocated based on the participation rights of both common shareholders and the holders of any participating securities as if earnings for the respective periods had been distributed. Because both the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis. For periods in which we have a net loss we do not use the two-class method as holders of our restricted shares are not obligated to share in such losses.

The presentation of basic EPS on the face of the accompanying condensed consolidated statements of operations is computed by dividing net income or loss by the weighted average shares of our common stock outstanding. The calculation of diluted EPS is similar to that for basic EPS, except that the denominator includes dilutive common stock equivalents and the numerator excludes the effects of dilutive common stock equivalents, if any. The computations of the numerator (income) and denominator (shares) to derive the basic and diluted EPS amounts presented on the face of the accompanying condensed consolidated statements of operations are as follows (in thousands):



	Three Months Ended March 31, 2019				Three Months Ended March 31, 2018
	Income			Shares	Income			Shares
Basic:
Net income (loss)	$	1,318			$	(2,560	)

Undistributed earnings (loss) allocated to common shares	$	1,306		147,421	$	(2,560	)	146,653

Diluted:
Undistributed earnings (loss) allocated to common shares	$	1,306		147,421	$	(2,560	)	146,653
Effect of dilutive securities:

We had a net loss for the three-month period ended March 31, 2018. Accordingly, our diluted EPS calculation for that period was equivalent to our basic EPS calculation since diluted EPS excluded any assumed exercise or conversion of common stock equivalents, which were deemed to be anti-dilutive. Shares that otherwise would have been included in the diluted per share calculations assuming we had earnings are as follows (in thousands):



	Three Months Ended
	March 31, 2018

Diluted shares (as reported)	146,653
Share-based awards	243
Total	146,896

In addition, the following potentially dilutive shares related to the 2022 Notes, the 2023 Notes and the 2032 Notes were excluded from the diluted EPS calculation as they were anti-dilutive (in thousands):



	Three Months Ended March 31,
	2019	2018

2022 Notes	8,997	8,997
2023 Notes	13,202	1,614
2032 Notes ⁽¹⁾	—	2,113
