Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk

We had cash, cash equivalents and short-term investments totaling $1,264.1 million as of June 30, 2022, of which $1,234.5 million was invested in money market funds, U.S. Treasury and agency securities. Our cash, cash equivalents and short-term investments are held for working capital and general corporate purposes. We do not enter into investments for trading or speculative purposes.

Our cash equivalents and short-term investments are subject to market risk due to changes in interest rates. Fixed rate securities may have their market value adversely affected due to a rise in interest rates. Due in part to these factors, our future investment income may fall short of our expectations due to changes in interest rates or we may suffer losses in principal if we are forced to sell securities that decline in market value due to changes in interest rates. As our short-term investments are classified as available-for-sale, no gains are recognized due to changes in interest rates. As losses due to changes in interest rates are generally not considered to be credit related, no losses in such investments are recognized due to changes in interest rates unless we intend to sell, it is more likely than not that we will be required to sell, we sell prior to maturity, or we otherwise determine that all or a portion of the decline in fair value is due to credit related factors.

As of June 30, 2022, a hypothetical increase of 100-basis points in interest rates would not have a material impact on the value of our cash equivalents or short-term investments in our unaudited Condensed Consolidated Financial Statements.

With the exception of the item above, there have been no material changes in our market risk exposures for the three months ended June 30, 2022, as compared to those discussed in our Form 10-K for the year ended December 31, 2021.
