|Share-based Compensation [Abstract]|
|Stock Plans [Text Block]||
The following table summarizes the stock-based compensation expense recorded for awards under the stock option plans for the three and nine-month periods ended September 30, 2018 and 2017:
No tax benefit was recognized related to stock-based compensation expense since we have accumulated operating losses and we have established a full valuation allowance to offset all the potential tax benefits associated with our deferred tax assets.
We use the Black-Scholes-Merton option-pricing model with the following assumptions to estimate the stock-based compensation expense for the three and nine-month periods ended September 30, 2018 and 2017:
No options were granted during the three-month period ended September 30, 2018. Options to purchase approximately 50,000 shares of common stock were granted during the three-month period ended September 30, 2017. Options to purchase approximately 950,000 and 546,000 shares of common stock were granted during the nine-month periods ended September 30, 2018 and 2017, respectively.
The following table summarizes option activity for the nine-month period ended September 30, 2018:
No shares of restricted stock were awarded to employees, directors and consultants during the three and nine-month periods ended September 30, 2018 and 2017.
As of September 30, 2018, there was approximately $0.3 million of total unrecognized compensation expense related to non-vested stock options. This expense is expected to be recognized over a weighted-average period of 0.3 years.
On August 7, 2018, our stockholders approved an amendment to the Titan Pharmaceuticals, Inc. 2015 Omnibus Equity Incentive Plan to increase the number of shares authorized for awards thereunder from 2,500,000 to 3,500,000.
