Series A Preferred Stock

Effective April 8, 2020, the Company exchanged an aggregate of approximately $7.0 million of all its then-outstanding notes, representing principal and accrued interest through April 7, 2020, for 1,391 shares Series A Preferred Stock. The shares of Series A Preferred Stock were recorded at fair value of $11.6 million (before reduction of $0.029 million related to issue costs) based on a per share fair value of $0.008 million. The per share fair value was determined using the number of common stock shares in a conversion (3,333 = $0.005 million original issue price divided by $1.50 conversion price) multiplied by the $2.50 market price of a share of common stock.

Each share of Series A Preferred Stock had a $0.005 million issue price. Dividends accrued on the issue price at a rate of 10.0% per annum and were payable to holders of Series A Preferred Stock when and if declared by the Board. The dividends were cumulative and accrued starting from the April 8, 2020 issuance date.

Each share of Series A Preferred Stock was convertible into the number of shares of common stock equal to the issue price divided by the conversion price of $1.50. Upon conversion of the Series A Preferred Stock, all accrued and unpaid dividends were converted to common stock utilizing the same conversion formula. The conversion price was subject to proportional adjustment for certain transactions relating to the Company’s common stock, including stock splits, stock dividends and similar transactions. Holders of Series A Preferred Stock were entitled to a liquidation preference in the event of any liquidation, dissolution or winding up of the Company.
