[1] | For the Company’s lease commitments as of December 31, 2023, refer to Note 10, “Leases.”
[2] | The above table does not reflect possible payments in connection with unrecognized tax benefits of approximately $110.7 million, including $31.7 million recorded as a reduction of long-term deferred tax assets and $78.9 million in long-term income taxes payable, as of December 31, 2023. As noted below in Note 18, “Income Taxes,” although it is possible that some of the unrecognized tax benefits could be settled within the next 12 months, the Company cannot reasonably estimate the timing of the outcome at this time.
[3] | In connection with the acquisitions of Hardent in the second quarter of 2022 and PLDA in the third quarter of 2021, the Company is obligated to pay retention bonuses to certain employees subject to certain eligibility and acceleration provisions, including the condition of employment.
[4] | In connection with the acquisition of AnalogX in the third quarter of 2021, the Company was obligated to pay retention bonuses to certain employees subject to certain eligibility and acceleration provisions, including the condition of employment. In September 2023, the Company divested its PHY IP group, which included AnalogX and resulted in the Company recognizing an immaterial decrease related to the remaining AnalogX acquisition retention bonus liability. Refer to Note 20, “Divestiture,” for additional information.
