debt vs equity

the normal because of the private equity LBO debt /?

Well, I thought that Google knows everthing, but I can not find the answer. I try to get an estimate of the normal (or maturity) of debt issued by companies to finance capital acquisitions, or tell LBO (LBO) deals. I that is 5 years, but maybe I'm wrong. I'm more interested in the current situation of the United States, but that would be great if someone can offer a perspective historical and global, and as a commentary on the motivation for choosing this particular period with another, or choose between a loan and debt.

A PE typical firm seeks to leverage its purchase with a combination of debt, bank debt can be ordinary and mezzanine funds. The first is issued bank rates, and maturity and may be stronger alliances. The latter, however, can be a source of funds by the EP of its own sources, which are usually provided at a rate of higher interest rates. Thus, the first may be a period of five years, subject to certain clauses tight. These may be the same length shorted. Much will depend on the exit strategy for private equity.
