Debt renegotiations are popular in practice; a key problem is how to specify their renegotiation time. We provide a new method to address the timing of debt renegotiations with the patterns of debt-equity swap, strategic debt service and distressed exchange respectively. We incorporate credible threats into debt renegotiations instead of non-credible threats implicit in much of previous literature. Our method derives that optimal renegotiation thresholds in the three renegotiation patterns are the common bankruptcy thresholds, which are less than the previous derived corresponding thresholds. Our method brings a higher optimal bond coupon rate and a much higher firm value than the previous studies. We produce analytical proofs for most of these conclusions.
