[1] | For the Company’s lease commitments as of September 30, 2023, refer to Note 8, “Leases.”
[2] | The above table does not reflect possible payments in connection with unrecognized tax benefits of approximately $104.4 million, including $27.4 million recorded as a reduction of long-term deferred tax assets and $77.0 million in long-term income taxes payable as of September 30, 2023. As noted below in Note 13, “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 outcome at this time.
[3] | The Company has commitments with various software vendors for agreements generally having terms longer than one year. As of September 30, 2023, approximately $16.0 million of the fair value of the software licenses was included in other current liabilities and $11.1 million was included in other long-term liabilities, in the accompanying Unaudited Condensed Consolidated Balance Sheet.
[4] | 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. (5) 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 includes AnalogX and resulted in the Company recognizing an immaterial decrease related to the remaining AnalogX acquisition retention bonus liability. Refer to Note 17, “Divestiture,” for additional information.I
