[5] The Company categorized its unitranche loans as First Lien Senior Secured Loans. The First Lien Senior Secured Loan is comprised of two components: a first out tranche (“First Out”) and last out tranche (“Last Out”). The Company syndicates the First Out tranche and retains the Last Out tranche. The First Out and Last Out tranches have the same maturity date. Interest disclosed reflects the contractual rate of First Lien Senior Secured Loan. The First Out tranche has priority as to the Last Out tranche with respect to payments of principal, interest and any amounts due thereunder. The Company may be entitled to receive additional interest as a result of the Agreement Among Lenders (“AAL”) entered into with the First Out lender. In exchange for the higher interest rate, the Last Out portion is at a greater risk of loss.
