We show that the structure and pricing of debt in LBOs mostly depend on a single characteristic of the target firm, pre-LBO profitability. We find a positive relationship between pre-LBO profitability and deal leverage that is consistent with a dynamic trade-off theory of capital structure in the presence of adjustment costs. We argue that the wide range of debt tranches used in LBO financing can be folded into two main categories, senior and junior debt, where the pricing of senior and junior debt depends on their relative use and on bankruptcy risk. Our evidence also suggests that senior lenders oversupply cheap credit during hot buyout markets.

By means of a difference-in-differences approach on the volatility of stock returns (σ-DID), we investigate the effect that hedging has on corporate risk. Examining the relation between hedging and the idiosyncratic variance of stock returns, we show that when new commodity derivatives are introduced in the Chicago Mercantile Exchange (CME), firms with exposure to the commodities experience up to a 40% drop in the idiosyncratic variance of stock returns. The effect is persistent over time and it is associated with real effects: firms that hedge more also experience an increase in profit margins, investment, access to credit lines, and a drop in cash holdings. Our results establish a direct link between corporate risk management policies and stock return behavior.
