In June 2017, our stockholders approved the 2017 Stock Incentive Plan (the “2017 Stock Plan”) with a maximum of 5,000,000 shares reserved for issuance. Awards permitted under the 2017 Stock Plan include: Stock Options and Restricted Stock. Awards issued under the 2017 Stock Plan are at the discretion of the Board of Directors. As applicable, awards are granted with an exercise price equal to the closing price of our common stock on the date of grant and generally vest over four years. During the years ended December 31, 2018 and 2017, 0.2 million and 0.5 million option awards were granted under the 2017 Stock Plan, respectively. At December 31, 2018, 0.7 million awards remain issued and outstanding.

During the years ended December 31, 2018 and 2017, the Company awarded 80,000 and 15,000 shares, respectively, of restricted stock to the Board of Directors and management under the 2017 Stock plan. The fair market value of restricted shares for share based compensation expensing is equal to the closing price of our common stock on the date of grant. The vesting on Restricted Stock Awards are typically released quarterly over three years for Board of Directors and annually over four years of management. During the year ended December 31, 2018, 18,753 shares of restricted stock vested. No shares of restricted stock vested during the year ended December 31, 2017. Restricted stock awards are issued to the recipient upon vesting and are not included in outstanding shares until such vesting and issuance occurs.

The Company previously reserved 3,000,000 shares of common stock for issuance under its 2005 Stock Option Plan (the “2005 Stock Plan”). The 2005 Stock Plan expired as of December 31, 2014. Vesting provisions of the expired plan were to be determined by the Board of Directors. All stock options under the 2005 Stock Plan expire no later than ten years from the date of grant. Options granted in 2015, 2016 and through May 2017 prior to the approval of the 2017 Stock Incentive Plan were approved and certified by the board of directors on September 6, 2017 under the existing 2005 stock option plan. At December 31, 2018, 1.2 million options remain issued and outstanding under the 2005 stock option plan.

During the year ended December 31, 2018 there were 0.2 million options granted, plus the aforementioned restricted stock grants. The options were granted at a weighted average exercise price of $2.99 per share. The weighted-average grant date fair value of options granted during the year ended December 31, 2018 was $2.65.

During the year ended December 31, 2017, the Company granted options to purchase up to 0.7 million shares of common stock to employees at a weighted average exercise price of $0.83 per share. The weighted-average grant date fair value of options granted during the year ended December 31, 2017 was $0.66.

The Company received proceeds of approximately $0.2 million and $39,000 related to option exercises during the years ended December 31, 2018 and 2017, respectively.

The Company uses the Black Scholes option pricing model to determine the fair value of stock option grants, using the following assumptions during the years ended December 31, 2018 and 2017:

	2018			2017
Weighted average expected term		6.25 years			6.25 years
Weighted average volatility		123	%		124	%
Weighted average risk-free interest rate		3.00	%		1.83	%
Dividend yield		0	%		0	%

The weighted average expected term of stock options represents the period of time that the stock options granted are expected to be outstanding based on historical exercise trends. The weighted average expected volatility is based on the historical price volatility of the Company’s common stock. The weighted average risk-free interest rate represents the U.S. Treasury bill rate for the expected term of the related stock options. The dividend yield represents the Company’s anticipated cash dividend over the expected term of the stock options. Forfeitures are accounted for as they occur.
