Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risks in the ordinary course of our business, which primarily relate to fluctuations in interest rates.

As of December 31, 2021, we had unrestricted cash and cash equivalents of $1.52 billion. A hypothetical 10% change in interest rates would not have a material impact on our financial condition or results of operations due to the short-term nature of our cash equivalents.

As of December 31, 2021, we had a debt balance of $3.27 billion. A hypothetical 50 basis point change in interest rates as of December 31, 2021 would not have a material impact on our consolidated financial statements for the year ended December 31, 2021.
