[2] The majority of certificates of deposit are foreign deposits.

[3] During 2023, the Company extended a credit facility to LCP with a total commitment of up to $5.0 million and maturities of greater than twelve months (the “LCP Notes Receivable”). Refer to “Note 12 — Growth Equity Fund” for further details. The LCP Notes receivable bear interest at an annual rate equal to 8%. As of June 30, 2024 and December 31, 2023, the LCP Notes Receivable in the amounts of $2.7 million and $1.8 million, respectively, were included in other assets within the condensed consolidated balance sheets. Fair values are based on discounted future cash flows using current interest rates offered for similar notes to third parties with similar credit ratings for the same remaining maturities.
