This document analyzes how debt renegotiation shapes the design of credit contracts. The author studies 1,500 loans between 1999-2014 in Europe. The results show that contractual frictions like shorter maturity, lack of collateral, and absence of a reputable lead bank lead to less extensive renegotiation packages. The legal environment also influences renegotiations - more creditor-friendly laws lead to more concessions during renegotiations and deeper reshaping of contracts. Lender financial strength similarly allows for more concessions, as sounder banks can accept larger changes to contracts.
