In connection with the June 2022 Private Placement, we paid the placement agent commissions of $252 thousand, plus $35 thousand in expenses, and we also paid legal, accounting and other fees of $47 thousand. Total offering costs of $334 thousand have been presented as a reduction of additional paid-in capital and have been netted within equity in the Condensed Consolidated Balance Sheet as of September 30, 2022.

In January 2022, all of the December 2021 Pre-Funded Warrants were exercised.

Preferred Stock

Pursuant to the terms of the Convertible Notes, on January 16, 2020, following approval by our stockholders of certain amendments to the Certificate of Incorporation, the principal amount of all of the Convertible Notes and the accumulated interest thereon at the date of conversion (totaling $1.8 million) were converted at a conversion price of $0.67 per share into an aggregate of 2,709,018 shares of the Company’s Series A Preferred Stock, which is convertible on a one-for-five basis into shares of our common stock. During the year ended December 31, 2020, 111,548 shares of the Series A Preferred Stock were converted into 22,310 shares of common stock. During the year ended December 31, 2021, 1,721,023 shares of Series A Preferred Stock were converted into 344,205 shares of common stock. The Series A Preferred Stock that was converted in 2021 was held by a Schedule 13D ownership group (under Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, and Rule 13d-5 promulgated thereunder) that includes Fusion Park LLC (“Fusion Park”) and 5 Elements Global Fund L.P. (controlled affiliates of James Tu, the Company's former Executive Chairman and Chief Executive Officer), as well as Brilliant Start Enterprise Inc. (“Brilliant Start”) and Jag International Ltd. (controlled affiliates of Gina Huang, a member of the Company's board of directors). Upon conversion of their respective shares of Series A Preferred Stock, Fusion Park and Brilliant Start received 184,851 and 159,354 shares, respectively, of the Company’s common stock.

The Series A Preferred Stock was created by the filing of a Certificate of Designation with the Secretary of State of the State of Delaware on March 29, 2019, which designated 2,000,000 shares of the Company’s preferred stock, par value $0.0001 per share, as Series A Preferred Stock (the “Original Series A Certificate of Designation”). On January 15, 2020 with prior stockholder approval, the Company amended the Certificate of Incorporation to increase the number of authorized shares of preferred stock to 5,000,000. The Original Series A Certificate of Designation was also amended on January 15, 2020, to increase the number of shares of preferred stock designated as Series A Preferred Stock to 3,300,000 (the Original Series A Certificate of Designation, as so amended, the “Series A Certificate of Designation”).

Pursuant to the Series A Certificate of Designation, each holder of outstanding shares of Series A Preferred Stock is entitled to vote with holders of outstanding shares of common stock, voting together as a single class, with respect to any and all matters presented to the stockholders of the Company for their action or consideration, except as provided by law. In any such vote, each share of Series A Preferred Stock shall entitle its holder to a number of votes equal to 11.07% of the number of shares of common stock into which such share of Series A Preferred Stock is convertible.

The Series A Preferred Stock (a) has a preference upon liquidation equal to $0.67 per share and then participates on an as-converted basis with the common stock with respect to any additional distributions, (b) shall receive any dividends declared and payable on our common stock on an as-converted basis, and (c) is convertible at the option of the holder into shares of our common stock on a one-for-five basis. On March 29, 2019, the Company also filed a Certificate of Elimination with respect to its authorized, but unissued, Series A Participating Preferred Stock, to return such shares to the status of undesignated preferred stock available for designation as Series A Preferred Stock.

The purchase agreement related to the Convertible Notes contains customary representations and warranties and provides for resale registration rights with respect to the shares of our common stock issuable upon conversion of the Series A Preferred Stock.

We also sold, to the same institutional investors, the Investor Warrants to purchase up to 688,360 shares of common stock at an exercise price of $3.37 per share in a concurrent private placement for a purchase price of $0.625 per warrant. We paid the placement agent commissions of $193 thousand, plus $50 thousand in expenses, in connection with the registered direct offering and the concurrent private placement and we also paid legal, accounting and other fees of $231 thousand related to the offering. Total offering costs of $510 thousand have been presented as a reduction of additional paid-in capital and have been netted within equity in the Condensed Consolidated Balance Sheet as of December 31, 2021.

Net proceeds to us from the sale of common stock and January 2020 Warrants were approximately $2.3 million.

January 2020 Warrants issued to purchase an aggregate of 229,414 shares remain outstanding at September 30, 2022 with a weighted average exercise price of $3.67 per share. The exercise of warrants could provide us with cash proceeds of up to $0.8 million in the aggregate if all warrants are exercised. During the nine months ended September 30, 2022, no January 2020 Warrants were exercised. During the nine months ended September 30, 2021, 156,446 warrants were exercised resulting in total proceeds of $527 thousand.

As of September 30, 2022 and 2021, we had the following outstanding January 2020 warrants to purchase shares of common stock:


	As of September 30, 2022	As of September 30, 2021
	Number of Underlying Shares		Exercise Price	Expiration
Investor Warrants	187,734	269,180	$3.3700	January 13, 2025
Placement Agent Warrants	41,680	41,680	$4.9940	January 13, 2025
	229,414	310,860

Warrant Classification

We account for common stock warrants as either liabilities or equity instruments depending on the specific terms of the warrant agreement. Common stock warrants that could require cash settlement are accounted for as liabilities and are revalued at fair value at each balance sheet date subsequent to the initial issuance. Changes in the fair market value of the warrant are reflected in the condensed consolidated statement of operations as income (expense) based upon the change in fair value of warrants. Common stock warrants without cash settlement provisions are accounted for as equity and re-measurement at each balance sheet date is not required.

Stock-based compensation

Stock-based compensation expense is attributable to stock options and restricted stock unit awards. For all stock-based awards, we recognize expense using a straight-line amortization method.

The following table summarizes stock-based compensation expense and the impact it had on operations for the periods presented (in thousands):


	Three months ended September 30,				Nine months ended September 30,
	2022		2021		2022		2021
Cost of sales	$	—	$	2	$	2	$	7
Product development	4		2		16		10
Selling, general, and administrative	13		35		97		370
Total stock-based compensation	$	17	$	39	$	115	$	387

Total unearned stock-based compensation was $0.2 million at September 30, 2022, compared to $0.3 million at September 30, 2021. These costs will be charged to expense and amortized on a straight-line basis in future periods. The weighted average period over which the unearned compensation at September 30, 2022 is expected to be recognized is approximately 2.5 years.

Stock options

The fair value of each stock option is estimated on the date of grant using the Black-Scholes option pricing model. Estimates utilized in the calculation include the expected life of the option, risk-free interest rate, and expected volatility, and are further detailed below.


	Nine months ended September 30,
	2022			2021
Fair value of options issued	$	0.77		$	4.18
Exercise price	$	0.95		$	5.39
