Item 7A. Quantitative and Qualitative Disclosures About Market Risk Interest Rate Risk We are exposed to market risk from changes in interest rates, primarily related to our investment activities. The principal objectives of our investment activities are to preserve principal, provide liquidity and maximize income consistent with minimizing risk of material loss. The recorded carrying amounts of cash and cash equivalents approximate fair value due to their short maturities. Our interest income is sensitive to changes in the general level of interest rates in the United States, particularly since our investments are generally short-term in nature. Based on the nature of our short-term investments, an immediate 100 basis point change in interest rates would not have a material effect on the fair market value of our portfolio. Inflation Inflationary factors, such as increases in our cost of revenue, sales and marketing expenses and reimbursement expenses, may adversely affect our operating results. Although we do not believe that inflation has had a material impact on our financial condition or results of operations to date, a high rate of inflation in the future may have an adverse effect on our ability to maintain and increase our gross margin, and on our sales and marketing and reimbursement expenses as a percentage of our revenue if the prices for our products do not increase as much or more than these increased costs. Credit Risk As of December 31, 2020 and 2019, our cash, cash equivalents and marketable securities were maintained with three financial institutions in the United States. We perform periodic evaluations of the relative credit standing of these financial institutions and believe they have sufficient assets and liquidity to conduct their operations in the ordinary course of business with little or no credit risk to us. We have not experienced any losses on our cash or cash equivalents to date. Our accounts receivable primarily relate to revenue from the sale of our products to patients in the United States. As of December 31, 2020 and 2019, our accounts receivable were $53.3 million and $37.6 million, respectively. We had accounts receivable from two insurers representing approximately 37% and 22% of accounts receivable as of December 31, 2020. We had accounts receivable from two insurers representing approximately 17% and 13% of accounts receivable as of December 31, 2019. The credit risks associated with customers which for these purposes are insurers considers aggregation for entities that are known to be under common control. Foreign Currency Risk Our business is conducted in U.S. dollars and international transactions have been nominal. As we begin building relationships to commercialize our products internationally, our results of operations and cash flows may become increasingly subject to changes in foreign exchange rates. 88 Table of Contents
