Deal Structure Types: Private, Institutional Debt, Institutional Equity, &amp; Institutional Debt &amp; Equity?
So I see there are 4 different types of capital structures available in a valuation model I'm trying to learn:

1) Private

2) Institutional Debt

3) Institutional Equity

4) Institutional Debt &amp; Equity

I can guess 'Private' means there is no debt financing and the deal is all cash or financed all by the company. ***However what do all the other deal structures mean?*** 

I notice also in the model that the Acquisition Fee is $0 if it is a private structured deal, but it is always 1% of acquisition price if the deal type is set kind of 'Institutional.' Does someone know why there would  be a different acquisition fee, or no acquisition fee based on a private vs institutional debt/financing structure?

Institutional usually just means that you received capital from a well established entity (again, if your taking a specific course or something they may be using it differently). If you'd like to send me the model I'd be happy to take a look, otherwise it's tough to understand exactly where you're coming from.", "replies": [], "depth": 1}]
