Per Share Data

Jun. 30, 2019

Basic net income (loss) per common share is computed by dividing net income (loss) attributable to the Company, decreased in the case of income and increased in the case of loss by dividends declared on preferred stock, by the weighted-average number of common shares outstanding.

The dilutive effect of incremental common shares potentially issuable under outstanding options and warrants and unvested restricted stock is included in diluted earnings per share utilizing the treasury stock method. A reconciliation of basic and diluted common shares used in the computation of per share data follows:



	Three Months Ended June 30,		Six Months Ended June 30, 2019
	2019	2018	2019	2018
Basic weighted-average shares	143,444,079	196,557,837	143,377,919	196,230,136
Effect of dilutive securities:
Options to purchase common stock	—	12,050,453	—	—
Restricted shares of common stock	—	1,247,646	—	—
Dilutive potential common shares	—	13,298,099	—	—
Weighted average common shares outstanding and dilutive potential common shares	143,444,079	209,855,936	143,377,919	196,230,136

Basic weighted-average shares do not include 5,336,500 and 4,366,520 unvested restricted shares of common stock for the three and six months ended June 30, 2019 and 2018, respectively.

For the three and six months ended June 30, 2019, options and warrants to purchase 17,997,111 shares of common stock and 5,336,500 unvested restricted shares of common stock were not included in the computation of diluted loss per share as the effect would have been anti-dilutive.

For the three months ended June 30, 2018, options to purchase 1,871,000 shares of common stock and for the six months ended June 30, 2018 options to purchase 27,304,117 shares of common stock and 4,366,520 unvested restricted shares of common stock were not included in the computation of diluted income (loss) per share as the effect would have been anti-dilutive.
