Item 7A.
Quantitative and Qualitative Disclosures About Market Risk.
Interest Rate Risk
We had cash and cash equivalents of $399.0 million and total investments of $203.5 million as of December 31, 2021. We hold our cash and cash equivalents for working capital purposes. Our cash and cash equivalents are held in cash deposits and money market funds. Our investments are held in commercial paper, corporate notes and bonds, municipal bonds, and U.S. government and agency securities. The primary objective of our investment activities is to preserve principal while at the same time maximizing yields without significantly increased risk. To achieve this object, we invest in highly liquid securities depending on our strategic cash needs. Due to the nature of these instruments, we believe that we do not have any material exposure to changes in the fair value due to changes in interest rates. Declines in interest rates, however, would reduce our future interest income. Further, in the event of a change of such magnitude, we would consider taking actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, the sensitivity analysis assumes no changes in our investment portfolio.
Concentration of Credit Risk
We deposit our cash, cash equivalents and investments with financial institutions, and, at times, such balances may exceed federally insured limits. Management believes the financial institutions that hold our cash, cash equivalents and investments are financially sound and, accordingly, minimal credit risk exists with respect to such balances.
