What are the formulas behind the YIELDDISC function?

[CPodd]

The YIELDDISC Function in EXCEL gives me my expected results. It is a great
ADD-IN Function. However, I have been asked to describe the Mathematical
Formulas behind this Function and YIELDDISC is a black box on this issue.

I know that it is based on IRR, but does anyone have a desciption (or a link
to a description) that would be more "Textbook"?

Thanks.

There's a lot of information on the function at this link, however, I don't
see any information on the math behind it:
