Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our primary market risks are exposures to changes in interest rates impacting our investment income and interest expense and the fair value of certain of our fixed-rate investments and debt.

As of December 31, 2024, we had $33 billion of financial assets on which the interest rates received vary with market interest rates, which may significantly impact our investment income. Also as of December 31, 2024, $27 billion of our financial liabilities, which include debt and deposit liabilities, were at interest rates which vary with market rates, either directly or through the use of related interest rate swap contracts.

The fair value of our fixed-rate investments and debt also varies with market interest rates. As of December 31, 2024, $46 billion of our investments were fixed-rate debt securities and $49 billion of our debt was non-swapped fixed-rate term debt. An increase in market interest rates decreases the market value of fixed-rate investments and fixed-rate debt. Conversely, a decrease in market interest rates increases the market value of fixed-rate investments and fixed-rate debt.

We manage exposure to market interest rates by diversifying investments across different fixed-income market sectors and debt across maturities, as well as by matching a portion of our floating-rate assets and liabilities, either directly or through the use of interest rate swap contracts. Unrealized gains and losses on investments in available-for-sale debt securities are reported in comprehensive income.

The following tables summarize the impact of hypothetical changes in market interest rates across the entire yield curve by 1% point or 2% points as of December 31, 2024 and 2023 on our investment income and interest expense per annum and the fair value of our investments and debt (in millions, except percentages):

Note: The impact of hypothetical changes in interest rates may not reflect the full 100 or 200 basis point change on interest income and interest expense or on the fair value of financial assets and liabilities as the rates are assumed to not fall below zero.

As of December 31, 2024, we had $4.9 billion of investments in equity securities, primarily consisting of venture investments and employee savings plan related investments.
