Compensation Actually Paid and Net Income (Loss)

Compensation Actually Paid and Net Income (Loss)

 

Due to the nature of the Company’s consolidated financial results and primary focus on research and development of diagnostic-guided therapy products to treat gastrointestinal diseases, our Company has not historically utilized net income (loss) as a performance measure for our executive compensation program. However, as the inFoods product has now launched, the Board will evaluate the relationship between our total revenues and net income (loss) and CAP to our PEO and Non-PEO NEOs going forward.

   
Total Shareholder Return Amount [3] $ 21.81 27.83 42.38
Net Income (Loss) Attributable to Parent [4] $ (3,775,000) $ (4,973,000) $ (5,978,000)

(3) The dollar amounts reported in columns (c) and (e) represent the CAP to Mr. Zackary Irani, and the average CAP to our non-PEO NEOs, respectively, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to our NEOs during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, to calculate CAP, compensation related to equity awards was remeasured based on the following: For stock options, a Black-Scholes (“BSM”) option-pricing model was used as of the applicable year-end date, or, in the case of vested options, the vesting date. The BSM model requires us to make assumptions and judgments regarding the variables used in the calculation, including the expected remaining term, expected volatility, and the expected risk-free rate. For restricted stock awards, the closing market price of the Company’s common stock was used as of the applicable year-end date, or in the case of vested restricted stock awards, the vesting date. The valuation assumptions used to calculate the CAP shown in the table were materially consistent with those used to calculate our share-based compensation expense, as disclosed in our Annual Report.
