PER SHARE DATA

Basic net income (loss) per share of common stock attributable to the Company is computed on the basis of the weighted average number of shares of common stock outstanding. Diluted net income (loss) per share is computed on the basis of such weighted average number of shares of common stock outstanding plus the dilutive effect of incremental shares of common stock potentially issuable under outstanding options, warrants and unvested restricted stock units utilizing the treasury stock method. A reconciliation of basic and diluted common shares used in the computation of per share data follows:



	Three Month Period Ended December 31,
	2018	2017
Basic weighted-average shares	12,545,286	12,437,916
Effect of dilutive securities:
Unvested restricted stock units	170,909	—
Diluted weighted-average shares	12,716,195	12,437,916

The following potential common share equivalents are not included in the above diluted computation because to do so would be anti-dilutive as the instruments are out of the money:
