In this paper, we analyze the key drivers of bond covenant prices by employing a novel measurement approach based on secondary market data. We find that covenant prices vary significantly over time and are associated with market-wide credit risk, volatility, and macroeconomic variables. Apart from the time-series dynamics, there is also significant variation across bond and firm characteristics. In particular, covenant prices increase with the riskiness of bonds and are higher for firms that have more growth options, more tangible assets, and are smaller. Furthermore, we document a positive correlation between the prices of covenants and their subsequent inclusion rates.

In January 2025, CRSP discontinued the existing stock tape used in many published papers. This transition rewrites 9.62% of monthly returns by more than 1 basis point (bp), primarily due to a change in the dividend reinvestment assumption. Analyzing the impact for a comprehensive set of premia in several thousand sorting specifications reveals that, on average, 11.43% of all monthly long-short returns differ by more than 10 bp—especially in early periods, NBER recessions, and return-based sorts. Reassuringly, average premia and their significance remain largely unaffected, suggesting CRSP changes mainly introduce unsystematic variation without altering key asset pricing conclusions.
