I've been through an LBO before, my first thought when I saw this news was: so eBay is going to have to pay interest on a $50B loan now?
eBay had $2B of net income in the last year. That might get them half-way to paying their annual interest payment if this deal closes. Get ready for the inevitable layoffs to cover that interest payment.
If there is iffy interest coverage for the debt and assets might be a stretch to cover (principal + interest), why will someone sponsor the debt here ?
Also, rates seems to be high, at least compared to recent history, to be favorable for this kind of LBO.
