Private Placement
 
On February 27, 2017, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain accredited investors, pursuant to which the Company agreed to issue and sell to the investors in a private placement (the “Private Placement”) an aggregate of 554,000 shares of the Company’s common stock at a purchase price of $5.00 per share. The Company closed the Private Placement on the same day as it entered into the Securities Purchase Agreement and received aggregate gross proceeds of approximately $2.8 million. In connection with the Private Placement, the Company paid an aggregate of $196,000 of financial advisory fees and $40,000 of administrative fees, which were recorded as a reduction of additional paid-in capital.
 
The Securities Purchase Agreement contains a “most-favored nation” provision that provides that if the Company, during 120 days from February 27, 2017, issues or sells any common stock or common stock equivalents reasonably believed to be more favorable in terms or conditions than those in the Private Placement, then the Company must amend the terms of the Securities Purchase Agreement to give the private investors the benefit of such favorable terms or conditions. In connection with the common stock sold in the Public Offering (as defined below) and in accordance with this provision, on April 11, 2017, the Company issued an aggregate of 38,072 shares of its common stock to these investors. On June 23, 2017, the Company held its 2017 annual meeting of stockholders during which the stockholders approved the issuance of the remaining 100,428 additional shares of common stock to be issued to the investors, and, following the meeting, on June 23, 2017, the Company issued the remaining shares.
 
Underwritten Public Offering
 
On April 3, 2017, the Company closed an underwritten public offering (the “Public Offering”) of 947,325 shares of its common stock at a price to the public of $4.00 per share. The Company received aggregate gross proceeds of approximately $3.8 million. In connection with the Public Offering, the Company paid an aggregate of $365,000 of financial advisory fees and $92,000 of administrative fees, which were recorded as a reduction of additional paid-in capital.

On April 3, 2017, the Company issued warrants to purchase an aggregate of 23,686 of the Company’s common stock to the underwriter of this offering. These warrants are immediately exercisable, have an exercise price of $4.40, and expire on March 29, 2022. The warrants had an aggregate issuance date fair value of $78,000 which was recorded as both a debit and credit to additional paid in capital.
 
Pursuant to an anti-dilution provision provided in the warrants dated November 8, 2012 to purchase common stock at an initial exercise price of $21.90, the exercise price of these warrants was adjusted to the public offering price of $4.00. As of April 3, 2017, November 2012 warrants to purchase 36,231 shares of the Company’s common stock were outstanding. These warrants expired in November 2017.

Stock Options
 
During 2016, the Company granted ten-year options to purchase an aggregate of 164,976 shares of common stock at exercise prices ranging from $8.00 to $22.00 with an aggregate grant date value of $1.3 million to employees and directors pursuant to the 2014 Plan. The options vest as follows: (i) 22,500 shares vest one-twelfth monthly over one year, and (ii) 142,400 shares vest ratably over three years on the anniversaries of the grant date. The grant date value is being amortized over the vesting term.
 
During 2017, the Company granted ten-year options to purchase an aggregate of 258,105 shares of common stock at exercise prices ranging from $2.09 to $5.70 per share with an aggregate grant date value of $642,000 to non-executive employees and directors pursuant to the 2014 Plan. The options vest as follows: (i) 45,045 shares vest one-twelfth monthly over one year, and (ii) 213,060 shares vest in one-fourth increments every six months over a period of two years. The grant date value is being amortized over the vesting term.
 
In applying the Black-Scholes option pricing model to stock options granted, the Company used the following assumptions:
 
 
 
Year Ended December 31,
 
 
 
2017
 
2016
 
Risk free interest rate
 
1.81% - 2.43%
 
1.14% - 2.06%
 
Expected term (years)
 
5.04 – 6.50
 
5.04 – 6.50
 
Expected volatility
 
81.94% - 87.00%
 
89.53% - 89.95%
 
Expected dividends
 
0.00%
 
0.00%
 
 
The risk-free interest rate is based on rates of treasury securities with the same expected term as the options. The Company uses the “simplified method” to calculate the expected term of employee and director stock-based options. The expected term used for consultants is the contractual life. The Company is utilizing an expected volatility figure based on a review of the Company’s historical volatility, over a period of time, equivalent to the expected life of the instrument being valued. The expected dividend yield is based upon the fact that the Company has not historically paid dividends, and does not expect to pay dividends in the near future.
 
Option forfeitures are estimated at the time of valuation and reduce expense ratably over the vesting period. This estimate will be adjusted periodically based on the extent to which actual option forfeitures differ, or are expected to differ, from the previous estimate, when it is material. The Company estimated forfeitures related to options at annual rates ranging from 0% to 5% for options outstanding at December 31, 2017 and 2016.
 
The weighted average estimated grant date fair value of the options granted during the years ended December 31, 2017 and 2016 was $2.49 and $7.73 per share, respectively.
