Investments in equity securities
On November 20, 2020, we entered into an agreement to make a minority equity investment of $2.0 million in Natural Fiber Welding, Inc. in exchange for 201,207 shares of Series A-3 Preferred Stock. Our investment is carried at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Throughout the year, we assess whether impairment indicators exist to trigger the performance of an impairment analysis. There were no impairment charges or observable price changes for the years ended December 31, 2021 and 2020.
On November 22, 2021, we made a $0.3 million investment in NoHo ESG, Inc. via a simple agreement for future equity (“SAFE”). The SAFE provides that we will automatically receive shares of the entity based on the conversion rate of future equity rounds up to a valuation cap. If there is a liquidity event, such as a change in control or initial public offering, we will have the option of receiving a cash payment equal to the purchase amount or receiving a number of shares of common stock based on the purchase amount divided by the liquidity price, assuming we fail to select the cash option. Our investment is carried at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Throughout the year, we assess whether impairment indicators exist to trigger the performance of an impairment analysis. There were no impairment charges or observable price changes for the year ended December 31, 2021.
