помогите, пожалуйста, с переводом project bond credit enhancement:

Текст о финансировании строительства сети железных дорог Европейским инвестиционным банком:

"This will be achieved by providing credit enhancement to those promoters, whose debt will effectively be divided into two tranches: senior and subordinated.

The subordinated debt, or Project Bond Credit Enhancement (PBCE) can take the form of a loan from the Bank, with the support of the European Commission and is given to the promoter at the outset. It may also take the form of a contingent credit line which can be drawn upon if the revenues generated by the project are not sufficient to ensure senior debt service.

The PBCE underlies the senior debt and therefore improves its credit quality, offering peace of mind to institutional investors"
