English to German Bus/Financial Finance (general)

Ich bin mir unsicher, wie ich diesen Begriff übersetzen soll, es könnte eine Bankbürgschaft gemeint sein. Hier der Kontext:

"A banking covenant is an undertaking that a bank imposes in order to lend money. Banking covenants will typically take the form of a financial measure that the company must achieve in order to secure the bank lending. For XXX plc our main banking covenant is that our total borrowing cannot be greater than 3.5 times our EBITDA – an accounting way of expressing profit."

Kann mir jemand helfen?
