[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 15 - Growth Equity Fund” for further details. The LCP Notes Receivable bear interest at an annual rate equal to 8%. As of December 31, 2024 and 2023, the LCP Notes Receivable in the amounts of $3.8 million and $1.8 million, respectively, were included in other assets within the 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.
