Our $186,000 investment in securities as of December 31, 2020 relates to 317,428 shares of preferred convertible debt of Zowie Technology Corporation (Taipei Hsien, Taiwan), a supplier of electronic component products (see Part I: Item 1 – Business – Suppliers) with our option after 3 (three) years to convert the investment into common stock or refundable bearing 7% annual interest rate. Our investment represents approximately 7.9% of their total outstanding shares although we do not have significant influence or control. This investment is accounted for under the cost (plus impairment) basis of accounting, however when facts and circumstances indicate that the carrying value of this asset may not be recoverable, we recognize an impairment loss. The impairment loss recognized is the amount by which the carrying amount exceeds the estimated fair value. In 2019, due to our estimated valuation assessment, we recognized an impairment loss of $193,000.
