Market-implied Ratings and Their Divergence from Credit Ratings
Iftekhar Hasan, Winnie P. H. Poon, Jianfu Shen, Gaiyan Zhang
Journal of Financial Research,
No. 2,
2023
Abstract
In this article, we investigate the divergence between credit ratings (CRs) and Moody's market-implied ratings (MIRs). Our evidence shows that rating gaps provide incremental information to the market regarding issuers' default risk over CRs alone in the short horizon and outperform CRs over extended horizons. The predictive ability of rating gaps is greater for more opaque and volatile issuers. Such predictability was more pronounced during the 2008 financial crisis but weakened in the post-Dodd-Frank Act period. This finding is consistent with credit rating agencies' efforts to improve their performance when facing regulatory pressure. Moreover, our analysis identifies rating-gap signals that do (do not) lead to subsequent Moody's actions to place issuers on negative outlook and watchlists. We find that negative signals from MIR gaps have a real economic impact on issuers' fundamentals such as profitability, leverage, investment, and default risk, thus supporting the recovery-efforts hypothesis.

Poison Bonds
Shuo Xia, Rex Wang Renjie
SSRN Discussion Paper,
2023
Abstract
This paper documents the rise of "poison bonds", which are corporate bonds that allow bondholders to demand immediate repayment in a change-of-control event. The share of poison bonds among new issues has grown substantially in recent years, from below 20% in the 90s to over 60% after 2005. This increase is predominantly driven by investment-grade issues. We provide causal evidence that the pressure to eliminate poison pills has led firms to issue poison bonds as an alternative. Further analyses suggest that this practice entrenches incumbent managers, coincidentally benefits bondholders, but destroys shareholder value. Holding a portfolio of firms that remove poison pills but promptly issue poison bonds results in negative abnormal returns of -7.3% per year. Our findings have important implications for understanding the agency benefits and costs of debt: (1) more debt does not necessarily discipline the management; and (2) even without financial distress, managerial entrenchment can lead to conflicts between shareholders and creditors.
