Investments, Debt and Equity Securities [Abstract]

Short-term investments that the Company has the positive intent and ability to hold to maturity are carried at amortized cost and classified as held-to-maturity. Short-term investments that are not classified as held-to-maturity are carried at fair value and classified as available-for-sale. As of September 27, 2024, all of the Company’s short-term investments were classified as available-for-sale. As of December 31, 2023, the Company did not have any short-term investments. Realized gains and losses on available-for-sale investments are included in net income. Unrealized gains and losses, net of tax, on available-for-sale investments are included in the condensed consolidated balance sheet as a component of accumulated other comprehensive income (loss).

As of September 27, 2024, the Company’s available-for-sale investments consisted of the following cost, unrealized positions and estimated fair value, disaggregated by class of instrument:

As of September 27, 2024, all of the Company’s available-for-sale investments were classified as short-term investments in the condensed consolidated balance sheet and had weighted average maturities of less than one year. The Company did not identify any other-than-temporary impairment on its available-for-sale investments during the first nine months of 2024.

The sale and/or maturity of available-for-sale investments resulted in proceeds of $55.6 million and $72.2 million during the third quarter of 2024 and the first nine months of 2024, respectively. There were no gross realized gains or losses in the third quarter of 2024 or the first nine months of 2024. There was no realized activity during the third quarter of 2023 or the first nine months of 2023, as the Company did not have any short-term investments during those periods.
