Item 7A. Quantitative and Qualitative Disclosures About Market Risk
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
Our exposure to market risk for changes in interest rates relates primarily to interest earned on our cash equivalents, investments and variable interest rate debt. The primary objective of our investment activities is to preserve our capital to fund operations. A secondary objective is to maximize income from our investments without assuming significant risk. Our investment policy provides for investments in low-risk, investment-grade debt instruments. As of December 31, 2022, we had $104.6 million in cash and cash equivalents and $3.4 million in our investment portfolio. Our cash equivalents are short-term investments with maturities of 90 days or less at the time of purchase. We maintain cash deposits in FDIC insured financial institutions in excess of federally insured limits. However, we believe that we are not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. As of December 31, 2022, our investment portfolio was comprised of available-for-sale securities, and we did not hold or issue financial instruments for trading purposes.
Interest Rate Risk – Cash
With the cash discussed above, our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S interest rates. However, we do not believe a sudden change in the interest rates would have a material impact on our financial condition or results of operations due to the short-term maturities on our cash equivalents. A hypothetical 100 basis point change in interest rates during any of the periods presented would not have had a material impact on our consolidated financial statements.
Interest Rate Risk – Cash Equivalents and Investment Portfolio
We invest a portion of our cash in a number of diversified fixed and floating rate securities, consisting of marketable debt securities and debt funds that are subject to interest rate risk. Changes in the general level of interest rates can affect the fair value of our investment portfolio. If interest rates in the general economy were to rise, our holdings could lose value. At December 31, 2022, a hypothetical increase in interest rates of 100 basis points across the entire yield curve on our holdings would not have resulted in a material impact on the fair value of our portfolio.
Interest Rate Risk – Variable-Rate Debt
Our use of variable-rate debt exposes us to interest rate risk as changes in interest rates would affect interest expense. As of December 31, 2022 , we have $475.0 million of variable-rate loans outstanding that mature on December 31, 2023. These loans bear interest at Term SOFR + 8.0%. As of December 31, 2022 , the interest rate on these loans was 12.59%. A hypothetical 100-basis point increase in the Term SOFR rate as of December 31, 2022 would increase our future interest payment by $4.8 million . Similarly, a hypothetical 100-basis point decrease in the Term SOFR rate as of December 31, 2022 would decrease our future interest payment by $4.8 million .
Foreign Currency Exchange Risk
We are exposed to foreign currency exchange rate risk inherent in conducting business globally in numerous currencies. We contract with clinical research organizations, investigational sites and suppliers in foreign countries. We are, therefore, subject to fluctuations in foreign currency rates in connection with these agreements. We have not entered into any material foreign currency hedging contracts although we may do so in the future. From inception through the date of this Annual Report, we have not incurred any material effects from foreign currency changes on these contracts. The effect of a 10% adverse change in exchange rates on foreign currency denominated cash and payables as of December 31, 2022 would not have been material. However, fluctuations in currency exchange rates could harm our business in the future.
We are also exposed to foreign currency fluctuations related to the operations of our subsidiary in Italy whose financial statements are denominated in the Euro. We translate all assets and liabilities denominated in foreign currency into U.S. dollars using the exchange rate as of the end of the reporting period, while the operating results are translated into U.S. dollars using the average exchange rates for the reporting periods. Gains and losses resulting from translating the financial statements from our subsidiary’s functional currency to U.S. dollars are recognized as a component of other comprehensive income (loss) , on the consolidated statement of comprehensive loss. Foreign currency exchange rate fluctuations affect our reported net loss and can make comparisons from period to period more difficult. Our foreign operations are not material to our operations as a whole. As such, we currently do not enter into currency forward exchange or option contracts to hedge foreign currency exposures.

Market Ris k
As of December 31, 2022, 9,090,909 warrants from the direct registered offering remained outstanding at a fair value of $21.6 million. The fair value of this warrant liability is determined using the Black-Scholes option pricing model and is therefore sensitive to changes in the market price and volatility of our common stock among other factors. In the event of a hypothetical 10% increase in the market price of our common stock ($5.58 based on the $5.07 market price of our stock at December 31, 2022) on which the December 31, 2022 valuation was based, the fair value of the warrant liability would have increased by $3.3 million. Similarly, based on the fair value of the warrants outstanding as of December 31, 2022, a hypo thetical decrease of 10% in the market price of our common stock would have the fair value of the warrant liability decreased by $3.3 million . S uch increase or decrease would have been reflected as change in fair value of warrant liability in other income (expense), net , in our consolidated statement of operations.
Inflation Risk
Inflation may affect us by increasing our cost of labor, clinical trial, and other costs. We do not believe that inflation has had a material effect on our business, financial condition or results of operations for any period presented herein.
