Item 7A. Quantitative and Qualitative Disclosures of Market Risk
Interest Rate Risk
We had cash and cash equivalents totaling $107.1 million as of December 31, 2021, the majority of which was invested in money market accounts. We also had marketable securities of $69.8 million which were invested in investment-grade corporate bonds, commercial paper and asset-backed securities. Such interest-earning instruments carry a degree of interest rate risk with respect to the interest income generated. Additionally, certain of these cash investments are maintained at balances beyond Federal Deposit Insurance Corporation, or FDIC, coverage limits or are not insured by the FDIC. Accordingly, there may be a risk that we will not recover the full principal of our cash investments. To date, fluctuations in interest income have not been significant. Because these accounts are highly liquid, we do not have material exposure to market risk. Our cash is held for working capital purposes. We do not enter into investments for trading or speculative purposes.
We did not have any outstanding debt under our $40.0 million revolving credit line as of December 31, 2021. The line of credit carries a variable interest rate equal to the greater of (i) 4.75% and (ii) (x) at any time when the Streamline Period is not in effect, one and one-half of one percent (1.50%) above the prime rate and (y) at any time when the Streamline Period is in effect, the prime rate and is available through January 31, 2022. See “—Liquidity and Capital Resources—SVB Credit Facility.”
We have not been exposed to, nor do we anticipate being exposed to, material risks due to changes in interest rates. A hypothetical 10% change in interest rates during any of the periods presented would not have had a material impact on our financial statements.
Foreign Currency Exchange Risk
We are not currently subject to significant foreign currency exchange risk as our U.S. and international sales are predominantly denominated in U.S. dollars. However, we have some foreign currency risk related to a small amount of sales denominated in Canadian dollars. Sales denominated in Canadian dollars reflect the prevailing U.S. dollar exchange rate on the date of invoice for such sales. Decreases in the relative value of the U.S. dollar to the Canadian dollar may negatively affect revenue and other operating results as expressed in U.S. dollars. We do not believe that an immediate 10% increase or decrease in the relative value of the U.S. dollar to the Canadian dollars would have a material effect on operating results.
We have not engaged in the hedging of foreign currency transactions to date. However, as our international operations expand, our foreign currency exchange risk may increase. If our foreign currency exchange risk increases in the future, we may evaluate the costs and benefits of initiating a foreign currency hedge program in connection with non-U.S. dollar denominated transactions.
