(1)All unrealized losses have been in a continuous loss position for less than 12 months. We do not intend to sell the investments in an unrealized loss position, and it is not more likely than not that we will be required to sell these investments before recovery of their amortized cost bases. (2)For six months ended June 30, 2023 and 2022, we sold cash equivalent investments for proceeds of $40.1 million and $19.0 million, respectively, and realized no gain or loss on such sales. The following table summarizes the contractual maturities of our cash equivalents and available-for-sale debt investments as of June 30, 2023:
