Note 10 - Stockholders’ equity


Controlled Equity Offering


On March 28, 2013, the Company entered into a Controlled Equity OfferingSM Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co., as sales agent (“Cantor”). Under the Sales Agreement, the Company may offer and sell, from time to time, through Cantor, shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), having an aggregate offering price of up to $20.0 million (the “Shares”). The Company will pay Cantor a commission of 3.0% of the aggregate gross proceeds received under the Sale Agreement. The Company is not obligated to make any sales of the Shares under the Sales Agreement. The offering of Shares pursuant to the Sales Agreement will terminate upon the earlier of (a) the sale of all of the Shares subject to the Sales Agreement or (b) the termination of the Sales Agreement by Cantor or the Company, as permitted therein. The Shares were initially issued pursuant to the Company’s Registration Statement which was declared effective on August 5, 2010 and the prospectus supplement, dated March 28, 2013, and more recently under a current registration statement declared effective August 13, 2013 and the prospectus supplement dated August 1, 2013, filed by the Company with the Securities and Exchange Commission.


On December 31, 2014, the Sales Agreement was amended in order for the Company to offer and sell, through Cantor, acting as agent, additional shares of Common Stock having an aggregate offering price of $20.0 million.  In connection with the amendment to the Sales Agreement, the Company also filed with the SEC a prospectus supplement dated December 31, 2014. 


For the year ended July 31, 2015, the Company sold an aggregate of 1,588,480 shares of common stock under the Sales Agreement at an average price of $4.34 per share and received proceeds of approximately $6.7 million, net of expenses of $207.

In fiscal 2015, the Company issued 214,984 shares of common for its employees’ 401(k) matching contributions obligation. The Company recorded an expense of $662 for the match, representing the fair value of the shares at the date of issuance.


In fiscal 2014, the Company issued 165,646 shares of common for its employees’ 401(k) matching contributions obligation. The Company recorded an expense of $636 for the match, representing the fair value of the shares at the date of issuance.

The Company recorded an expense of $616 for the match, reducing treasury stock by $3,074 for the average acquisition cost of such shares and adjusting additional paid in capital by $2,458.


Incentive stock plans


The Company has an incentive stock option and restricted (non-vested) stock award plan (the “2005 Plan”), under which the Company may grant options and restricted stock (non-vested) awards for up to 1,000,000 common shares under the 2005 Plan. 0 additional awards may be granted under the 2005 Plan. On January 14, 2011, the Company’s stockholders approved the adoption of the 2011 Incentive Plan (the “2011 Plan”) which provides for the issuance of equity awards, including among others, options, restricted stock and restricted stock units for up to 3,000,000 Common Shares. The exercise price of options granted under the 2011 Plan, and consistent with other Plans, is equal to or greater than fair market value of the Common Stock on the date of grant. Unless terminated earlier by the Board of Directors, the 2011 Plan will terminate at the earliest of; (a) such time as 0 shares of Common Stock remain available for issuance under the 2011 Plan or (b) tenth anniversary of the effective date of the 2011 Plan. Awards outstanding upon expiration of the 2011 Plan shall remain in effect until they have been exercised, terminated, or have expired. As of July 31, 2015, there were approximately 1,301,000 shares available for grant under the 2011 Plan.


The Company estimates the fair value of each stock option award on the measurement date using a Black-Scholes option pricing model. The fair value of awards is amortized to expense on a straight line basis over the requisite service period. The Company expenses restricted stock awards based on vesting requirements, primarily time elapsed.


Options granted pursuant to the plans may be either incentive stock options or non-statutory options The 2011 Plan provides for the issuance of stock options, restricted stock and restricted stock unit awards which generally vest over a two to four year period. A summary of the activity pursuant to the Company’s stock option plans for the years ended July 31, 2015, 2014, and 2013 is as follows:
