How do you model Schuldscheindarlehen in a DACH LBO schedule?

Model Schuldscheindarlehen as debt tranches with their own maturity, coupon, fixed / floating rate, amortization profile, and covenant terms. Include them in gross debt and net debt. Check change-of-control, prepayment, and refinancing provisions. In DACH deals, SSDs may sit beside bank debt and bonds and can affect covenant headroom.
