ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The primary objective of our short-term investment activities is to preserve principal while concurrently maximizing the income we receive from our equity securities without significantly increasing risk. Some of the securities that we invest in may be subject to interest rate risk and/or market risk. This means that a change in prevailing interest rates, with respect to interest rate risk, or a change in the value of the United States equity markets, with respect to market risk, may cause the principal amount or market value of the equity securities to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the then-prevailing rate and the prevailing interest rate later rises, the current value of the principal amount of our investment may decline. To minimize these risks in the future, we intend to maintain our portfolio of cash equivalents and equity securities in a variety of securities. Cash equivalents are comprised of investments in U.S. treasury securities and AAA rated money market funds that invest in first-tier only securities, which primarily include domestic commercial paper and securities issued or guaranteed by the U.S. government or its agencies. In general, money market funds are not subject to market risk because the interest paid on such funds fluctuates with the prevailing interest rate. Accordingly, a 100 basis point increase in interest rates or a 10% decline in the value of the United States equity markets would not be expected to have a material impact on the value of such money market funds. Declines in interest rates over time will, however, reduce our interest income.
Investment Risk
We are exposed to investment risks related to changes in the underlying financial condition of certain of our equity investments in technology companies. The fair value of these investments can be significantly impacted by the risk of adverse changes in securities markets generally, as well as risks related to the performance of the companies whose securities we have invested in, risks associated with specific industries, and other factors. These investments are subject to significant fluctuations in fair value due to the volatility of the securities markets and of the underlying businesses.
As of December 31, 2024 and 2023, the carrying value of our equity investments in public and private companies was $59.9 million and $99.8 million, respectively.
We record our equity investments in publicly traded companies at fair value, which are subject to market price volatility. As of December 31, 2024, a hypothetical 10% adverse change in the market price of our investments in publicly traded common stock would have resulted in a decrease of approximately $2.3 million in such equity investments. We evaluate our equity investments in private companies for impairment when events and circumstances indicate that the decline in fair value of such assets below the carrying value is other-than temporary.
Foreign Currency Exchange Risk
Although we historically have not had material foreign operations, we are also exposed to market risks related to fluctuations in foreign currency exchange rates between the U.S. dollar, and the British Pound and Euro currency exchange rates, primarily related to foreign cash accounts. As of December 31, 2024, we did not have any foreign denominated equity securities.
