Item 7A. Quantitative and Qualitative Disclosures About Market Risk
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to market risks in the ordinary course of our business. These risks primarily include interest rate risk, investment risk, and foreign currency risk as follows:
Interest Rate Risk
Our exposures to market risk for changes in interest rates relate primarily to our 2025 Refinanced Term Loan and 2027 Refinanced Term Loan Facilities. The 2025 and 2027 Refinanced Term Loan Facilities represent floating rate notes and are carried at amortized cost. Therefore, fluctuations in interest rates will impact our consolidated financial statements. A rising interest rate environment will increase the amount of interest paid on these loans. A hypothetical 100 basis point increase or decrease in interest rates would not have a material effect on our financial results.
The fair value of our fixed rate notes will generally fluctuate with movements of interest rates, increasing in periods of declining rates of interest and declining in periods of increasing rates of interest. A hypothetical 100 basis point increase in interest rates would have decreased the fair value of our notes by $317 million as of December 31, 2021.
Investment Risk
Our investment policy objective aims to preserve capital and meet liquidity requirements without significantly increasing risk. We had cash and cash equivalents including restricted cash and cash equivalents totaling $7.4 billion and $7.8 billion as of December 31, 2020 and December 31, 2021, respectively. We did not have any marketable debt securities classified as short-term investments as of December 31, 2021. Our cash and cash equivalents consist of money market funds and cash deposits. We do not enter into investments for trading or speculative purposes. Investments in fixed rate securities carry a degree of interest rate risk. Changes in rates would primarily impact interest income due to the relatively short-term nature of our investments. A hypothetical 100 basis point change in interest rates would not have a material effect on our financial results.
We are exposed to certain risk related to the carrying amounts of investments in other companies, including our minority-owned, privately-held affiliates and recently public companies, compared to their fair value. We hold privately held investments in illiquid private company stock which are inherently difficult to value given the lack of publicly available information. We also hold equity securities with readily determinable fair values which are subject to equity price risk. These investments in privately-held affiliates and recently public companies may increase the volatility in our net income/(loss) in future periods due to changes in the fair value of these investments. In certain cases, our ability to sell these investments may be impacted by contractual obligations to hold the securities for a set period of time after a public offering. As of December 31, 2021, the carrying value of our investments was $12.6 billion, including equity method investments.
Foreign Currency Risk
We transact business globally in multiple currencies. Our international revenue, as well as costs and expenses denominated in foreign currencies, expose us to the risk of fluctuations in foreign currency exchange rates against the U.S. dollar. We are exposed to foreign currency risks related to our revenue and operating expenses denominated in currencies other than the U.S. dollar. Accordingly, changes in exchange rates may negatively affect our future revenue and other operating results as expressed in U.S. dollars. Our foreign currency risk is partially mitigated as our revenue recognized in currencies other than the U.S. dollar is diversified across geographic regions and we incur expenses in the same currencies in such regions.
We have experienced and will continue to experience fluctuations in our net income/(loss) as a result of transaction gains or (losses) related to remeasurement of our asset and liability balances that are denominated in currencies other than the functional currency of the entities in which they are recorded. Foreign currency rates may also impact the value of our equity method investment in our Yandex.Taxi joint venture. At this time, we do not, but we may in the future, enter into derivatives or other financial instruments in an attempt to hedge our foreign currency exchange risk.
