Measure risk for increased bond yield
I'm looking at measuring the cost of debt for the restructuring of a company's bonds. The company is private, and comps are hard to come by. I'm finding new high yield issues but the tenors of the bonds are around 6-7 years, this restructuring will be around 25-30 years in total maturity. Any ideas on what increased spread to use or how to go about measuring the higher yield as a result of the lengthened tenor?
