We analyze how Dodd-Frank-mandated risk retention affects the information investors extract from issuers’ retention choices in the CMBS market. We show that the required retention level is both binding and stringent. Although this implies issuers cannot signal using the level of retention, we provide a model showing that signaling can occur by varying the retention structure. The model is consistent with spreads being empirically lower in deals with a purely first-loss retention structure. A stated concern of rulemakers is asymmetric information. However, we show that, post-crisis, the level of asymmetric information in this market is quite low.

We show that commercial mortgage borrowers behave opportunistically to attempt to obtain principal reductions. We develop a model in which lenders cannot perfectly observe borrowers’ use values and renegotiation is costly. We then exploit a tax rule change that reduced the cost of renegotiation. Consistent with the model predictions, borrowers with high private use values of the property are more likely to transfer into special servicing when lenders have a higher capacity to negotiate principal reductions after the rule change. Our results suggest adverse consequences of principal forgiveness for lenders.
