| (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 4.6% is used to calculate the interest component of rent expense. The borrowing rate is calculated using a weighted average for the interest rate on the Company's revolving line of credit of 4.4% and credit facility with the Bank of China of 4.7%. For the years prior to 2019, represents one-third of total rent expense which we believe is a reasonable estimate of the interest component of rent expense.

| (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.
