| (1) | Dividends accrue on our outstanding Series A preferred stock at the rate of $0.20 per annum per share of Series A preferred stock. We have not paid any dividends on preferred stock. 883,000 shares of our preferred stock were issued and outstanding for all of the periods presented. |
| (2) | Effective January 1, 2019 and onwards, interest is calculated consistent with guidance under ASC 842, where an estimate for the Company's incremental borrowing rate of 5.12%. The borrowing rate is calculated using a weighted average for the interest rate on the Company's Fremont office lease of 5.5% and the interest rate on Tongmei’s nitrogen system of 4.7%. |
| (3) | For periods in which there is a deficiency of earnings available to cover combined fixed charges and preferred stock dividends, the ratio information is not applicable. |
