Protections have gotten so lax in the $1 trillion market for U.S. leveraged loans that if an offering comes with decent covenants, lenders take it as a sign that something's wrong with the deal.

“You do have to think twice when you see a loan with a covenant these days,” says Thomas Majewski, managing partner and founder of Eagle Point Credit Management.

It's not a crazy assumption in a market where 75% of new loans are now defined as “covenant-lite,” meaning a company could, for example, rack up as much debt as it wants regardless of its performance. In such a lenient atmosphere, the reasoning goes, a loan must be a stinker if a borrower has to resort to promising even standard protections.
