11. Stockholders’ Equity

2014 Private Placement

During the three-month period ended March 31, 2014, we issued and sold for cash an aggregate 11,299,999 shares of our common stock at a purchase price of $0.30 per share in the 2014 private placement that resulted in gross proceeds of $3,390,000 (See Note 4).

The 2014 private placement was recorded into the financial statements as follows:

Gross cash proceeds	$	3,390,000
Less: gross proceeds allocated to warrants liability – investors		(1,356,000	)
Gross proceeds allocated to additional paid-in capital and common stock		2,034,000
Less: cash issuance costs – legal fees		(20,000	)
Recorded in additional paid-in capital and common stock	$	2,014,000

In conjunction with the 2014 private placement, we recorded a warrants liability of $1,356,000 as of January 7, 2014 on our Balance Sheet. Certain conditions under the SPA which expired on January 7, 2015 would have required us to issue additional warrants at below-market value exercise price (see Note 4). These conditions did not occur and ended as of January 7, 2015. Therefore, we have reclassified the related liability to equity as of January 7, 2015 on our Balance Sheet.

Accounting fees associated with the 2014 private placement, which aggregated approximately $9,600, were deemed immaterial and were charged to operating expense during the three-month period ended March 31, 2014.

Stock Repurchase Program

During each of the three-month periods ended March 31, 2015 and 2014, we did not repurchase any of our common stock under the terms of our Board-approved $1,000,000 stock repurchase program (“stock repurchase program”). As of March 31, 2015, approximately $782,600 remained available for future purchases under this program. We are not obligated to repurchase any specific number of shares and the stock repurchase program may be suspended or terminated at our discretion.
