We limit the credit risk associated with our cash equivalents and short-term investments by placing them with banks and institutions we believe are highly credit-worthy and investing in highly-rated investments. As of September 30, 2024, and December 31, 2023, the contractual maturity of all investments held was less than one year. During the three and nine months ended September 30, 2024 and 2023, we did not recognize any significant credit losses nor other-than-temporary impairment losses on our short-term investments.
