[1] | For the Company’s lease commitments as of June 30, 2024, refer to Note 9, “Leases.”
[2] | The above table does not reflect possible payments in connection with unrecognized tax benefits of approximately $121.3 million, including $28.6 million recorded as a reduction of long-term deferred tax assets and $92.7 million in long-term income taxes payable as of June 30, 2024. 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 timing of the outcome at this time.
[3] | The Company has commitments with various software vendors for agreements generally having terms longer than one year.
[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.
