FCFE for determining yearly long-term growth rate in a restructuring company

Hey mates!

I'm new to the forum - so hello to ya'll!

I'm also relatively new to the corporate finance world, so take it easy on me ;)

I have a question to you regarding the FCFE growth rate model!

I am doing some case problems to learn about valuing companys and one case problem wants to have the yearly long-term growth rates for a 10 years period. At the moment, the company is in a restructuring phase which should be finished 6 years after the the last period I have to consider for my problem.

Since the FCFE is not suitable for this problem as I am missing the net debt issued and also the debt financing, do you know other good methods for determine the longterm growth rate?

Second question: How can I derive the actual leverage of a company from the net financial leverage? Given is debt, spread, equity, and different ratios (ROE, ROA, NOPAT margin etc?)

I hope my question is stated in a clear way.

Thanks in advance for your efforts!
