Cash, cash equivalents, and restricted cash are placed with high-credit quality financial institutions and invested in high-credit quality money market funds and commercial paper.

On a loan-by-loan basis, the Company, at its option, can indemnify a portion of MTRCC’s guarantee obligation of loan opportunities presented to and closed by MTRCC through the DUS Agreement.

For the three and nine months ended September 30, 2024 and 2023, no transaction represented 10% or more of total revenue. Further, while one or more transactions may represent 10% or more of commissions receivable at any reporting date, amounts due for brokerage and financing transactions are typically collected within 10 days of settlement and, therefore, do not expose the Company to significant credit risk. </span></div><div style="margin-top:12pt;text-indent:22.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">During the three and nine months ended September 30, 2024, the Company’s Canadian operations represented 3.8% and 4.9% of total revenue, respectively.
