[1] | For the Company’s lease commitments as of September 30, 2022, refer to Note 9, “Leases.”
[2] | The Company’s other contractual obligations as of September 30, 2022 were not material.
[3] | The above table does not reflect possible payments in connection with unrecognized tax benefits of approximately $21.6 million, including $19.7 million recorded as a reduction of long-term deferred tax assets and $1.9 million in long-term income taxes payable as of September 30, 2022. As noted below in Note 14, “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.

During the second quarter of 2022, the Company renewed a software license agreement for engineering development tools, which is included in the table above. As of September 30, 2022, approximately $9.1 million of the fair value of this software license was included in other current liabilities and $17.2 million was included in other long-term liabilities, in the accompanying unaudited condensed consolidated balance sheet.
[6] | In connection with the acquisition of Northwest Logic in the third quarter of 2019, the Secure Silicon IP and Protocols business in the fourth quarter of 2019, the acquisitions of AnalogX and PLDA in the third quarter of 2021, and the acquisition of Hardent in the second quarter of 2022, the Company is obligated to pay retention bonuses to certain employees subject to certain eligibility and acceleration provisions, including the condition of employment.
