At September 30, 2023, we determined it was more likely than not we would sell our investments before recovery of their amortized cost basis. In the three months ending September 30, 2023, we wrote down the amortized cost basis of our investments to fair value and reclassified $734 in net unrealized losses out of accumulated comprehensive income into other income, net in the consolidated statements of net income and comprehensive income.
