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 March 31,		Six Month Period Ended March 31,
	2019	2018	2019	2018
Basic weighted-average shares	12,714,002	12,457,043	12,628,606	12,447,321
Effect of dilutive securities:
Unvested restricted stock units	—	—	—	—
Diluted weighted-average shares	12,714,002	12,457,043	12,628,606	12,447,321

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 and the Company is at a net loss position for these periods:



	Three Month Period Ended March 31,		Six Month Period Ended March 31,
	2019	2018	2019	2018
Options	610,200	612,000	610,200	618,000
Warrants	5,398,907	12,437,916	8,917,667	12,437,916
Unvested restricted stock units	249,332	291,082	124,666	184,410
