Share-based Compensation [Abstract]

3. Stock-Based Compensation

During the six months ended June 30, 2017, the Company had two shareholder–approved stock-based compensation plans. The 2006 Stock Incentive Plan was adopted in 2006 (“2006 Plan”) and had options granted under it through April 12, 2016. On June 1, 2016, the shareholders ratified the IAI 2016 Stock Incentive Plan (“2016 Plan”), which had been approved by the Board of Directors on April 4, 2016.

2016 Stock Incentive Plan

The 2016 Plan became effective June 1, 2016, and expires April 4, 2026. The 2016 Plan provides for the granting of equity awards to key employees, including officers and directors. Options under the 2016 Plan are generally granted at-the-money or above, expire no later than ten years from the date of grant or within three months of when employment ceases, whichever comes first, and vest over periods determined by the Board of Directors. The number of shares subject to options available for issuance under the 2016 Plan cannot exceed 1,000,000. At June 30, 2017, there were no options issued under the 2016 Plan.

2006 Stock Incentive Plan

The 2006 Plan became effective May 18, 2006, and expired April 12, 2016. The 2006 Plan provides for the granting of equity awards to key employees, including officers and directors. Options under the 2016 Plan were generally granted at-the-money or above, expire no later than ten years from the date of grant or within three months of when employment ceases, whichever comes first, and vest over periods determined by the Board of Directors. The number of shares subject to options available for issuance under the 2006 Plan could not exceed 1,950,000. There were 1,072,500 and 1,200,500 unexpired options remaining from the 2006 Plan at June 30, 2017 and 2016, respectively.

The Company estimates the fair value of options granted using a Black-Scholes valuation model to establish the expense. When stock-based compensation is awarded to employees, the expense is recognized ratably over the vesting period. When stock-based compensation is awarded to non-employees, the expense is recognized over the period of performance. The fair values of option awards granted in the three months and six months ended June 30, 2017 and 2016, were estimated using the Black-Scholes option pricing model using the following assumptions:

	Three Months ended June 30,		Six Months ended June 30,
	2017	2016	2017	2016
Risk free interest rate	n/a	0.70% - 1.73%	n/a	0.70% - 1.73%
Dividend yield	n/a	0%	n/a	0%
Expected term	n/a	2-10 years	n/a	2-10 years
Expected volatility	n/a	35.9% - 50.4%	n/a	34.9% - 50.4%

A summary of the activity under the stock incentive plans as of June 30, 2017, and changes during the six months then ended is presented below.

Incentive Options	Shares			Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term		Aggregate Intrinsic Value
Outstanding at January 1, 2017		1,313,000		$	0.22
Granted		-			-
Exercised		-			-
Expired		(220,500	)		0.40
Forfeited		(20,000	)		0.13
Outstanding at June 30, 2017		1,072,500		$	0.18		5.6	$	128,198
Exercisable at June 30, 2017		1,062,500		$	0.18		5.6	$	126,598

There were no options granted during the six months ended June 30, 2017, and the weighted-average grant date fair value of options granted during both the three months and six months ended June 30, 2016, was $0.04. There were no options exercised during the six months ended June 30, 2017 and 2016. As of June 30, 2017, there was $187 of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the stock incentive plans; that cost is expected to be recognized over a weighted-average period of five months.

Total compensation expense related to these plans was $63 and $4,806 for the quarters ended June 30, 2017 and 2016, respectively, none of which related to options awarded to non-employees. Total compensation expense related to these plans was $322 and $5,472 for the six months ended June 30, 2017 and 2016, respectively, none of which related to options awarded to non-employees. Compensation expense relating to prior periods in the amount of $612 was reversed in the six months ended June 30, 2017, from options that were forfeited prior to vesting, and are not included in the total compensation expense above.

Nonvested option awards as of June 30, 2017 and changes during the six months ended June 30, 2017 were as follows:

	Shares			Weighted average grant date fair value
Nonvested at January 1, 2017		45,000		$	0.07
Granted		-
Vested		(15,000	)		0.06
Forfeited		(20,000	)		0.04
Nonvested at June 30, 2017		10,000		$	0.05
