Issue:
Singular of "tranches" should be "tranche"
SIngularizing "tranches" as a noun results in "tranch", which is incorrect. The correct singularization is "tranche".

Tranche has French etymology, but is a [well-known word in English](https://www.merriam-webster.com/dictionary/tranche), especially in finance.
