Item 3.
Quantitative and Qualitative Disclosures About Market Risk
We are exposed to market risks in the ordinary course of our business. These market risks are principally limited to interest rate fluctuations. We had cash, cash equivalents and investments of $249.8 million at June 30, 2020, consisting primarily of funds in a money market account, corporate and municipal bonds and United States Treasury securities. The primary objective of our investment activities is to preserve principal and liquidity while maximizing income without significantly increasing risk. We do not enter into investments for trading or speculative purposes. Due to the short-term nature of our investment portfolio, we do not believe an immediate 1.0% increase in interest rates would have a material effect on the fair market value of our portfolio, and accordingly we do not expect a sudden change in market interest rates to affect materially our operating results or cash flows.
Our 2021 Convertible Notes and 2022 Convertible Notes bear interest at a fixed rate and therefore a change in interest rates would not impact the amount of interest we would have to pay on this indebtedness.
