Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Money Market Investments
We maintain an investment portfolio consisting
of U.S. or Canadian obligations and bank securities and money market investments in compliance with our investment policy. We do
not hold any mortgaged-backed investments in our investment portfolio. Securities must have a minimum Dun & Bradstreet
rating of A for bonds or R1 low for commercial paper. The policy also provides for investment limits on concentrations of securities
by issuer and maximum-weighted average time to maturity of twelve months. This policy applies to all of our financial resources.
At
December 31, 2020, we had $29.6 million in money market investments and savings accounts as compared to $13.3 million
at December 31, 2019; these investments typically have minimal risk. We have not experienced any loss or write
down of our money market investments for the years ended December 31, 2020 and 2019; however, the amounts we hold in money
market accounts are substantially above the $250,000 amount insured by the FDIC and may lose value.

Our investment policy is to manage investments
to achieve, in the order of importance, the financial objectives of preservation of principal, liquidity and return on investment. Our
risk associated with fluctuating interest rates on our investments is minimal and not significant to the results of operations. We
currently do not use interest rate derivative instruments to manage exposure to interest rate changes. As our main purpose
is research and development, we have chosen to avoid investments of a trade or speculative nature.
Foreign Currency Exposure
We are subject to foreign currency risks
as we purchase goods and services which are denominated in Canadian dollars. To date, we have not employed the use of derivative
instruments; however, we do hold Canadian dollars which we use to pay vendors in Canada and other corporate obligations. At
December 31, 2020, we held approximately Can$59,000.
