Sep. 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 September 30,		Nine Months Ended September 30, 2019
	2019	2018	2019	2018
Basic weighted-average shares	143,092,912	196,381,910	143,281,873	196,281,283
Effect of dilutive securities:
Options to purchase common stock	4,310,499	10,616,368	—	—
Restricted shares of common stock	556,598	1,388,958	—	—
Dilutive potential common shares	4,867,097	12,005,326	—	—
Weighted average common shares outstanding and dilutive potential common shares	147,960,009	208,387,236	143,281,873	196,281,283

Basic weighted-average shares do not include 5,336,500 and 4,215,270 unvested restricted shares of common stock for the three and nine months ended September 30, 2019 and 2018, respectively.

For the three months ended September 30, 2019, options to purchase 7,894,000 shares of common stock and 2,921,250 unvested restricted shares of common stock and for the nine months ended September 30, 2019, options to purchase 17,424,872 shares of common stock and 5,336,500 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.

For the three months ended September 30, 2018, options to purchase 4,289,000 shares of common stock and 437,000 unvested restricted shares of common stock and for the nine months ended September 30, 2018 options to purchase 26,371,583 shares of common stock and 4,215,270 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.
