Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Item 7A. Quantitative and Qualitative Disclosures About Market Risk.
Our current investment policy is to maintain a diversified investment portfolio consisting of money market investments, commercial paper, government and government agency bonds and high-grade corporate bonds with maturities of 36 months or less. Our cash is deposited in and invested through highly rated financial institutions in the United States. As of December 31, 2020, we had $1,947.8 million of cash, cash equivalents and investments, comprised of $1,502.6 million of cash and cash equivalents, $435.9 million short-term investments and $9.3 million of restricted cash and investments. The Company only holds debt securities classified as available-for-sale. The fair value of cash equivalents and short-term investments is subject to change as a result of potential changes in market interest rates. The potential change in fair value for interest rate sensitive instruments has been assessed on a hypothetical 10 basis point adverse movement across all maturities. For the years ended December 31, 2020 and 2019, we estimate that such hypothetical adverse 10 basis point movement would result in a hypothetical loss in fair value of approximately $0.2 million and $0.1 million, respectively, to our interest rate sensitive instruments.
