Principal customers have strong incentives to screen and/or monitor suppliers to ensure supply-chain stability; consequently, the implicit certification from the existence of long-term relationships with principal customers has reputational consequences that potentially spill over to other markets. We argue that one such consequence is smaller loan spreads and looser loan covenants on bank loans, as firms that are able to hold on to principal customers longer are perceived as safer firms by banks. We address causality and endogeneity issues via a variety of tests and find consistent results. Our study suggests that non-financial stakeholders can have important effects on the decisions of financial stakeholders.

In a model of dual-agency problems where borrower–lender and bank–nonbank incentives may conflict, we predict a hockey stick relation between bank skin in the game and covenant tightness. As bank participation declines, covenant tightness increases until reaching a low threshold, at which point the relation sharply reverses and covenant protection is removed with a commensurate increase in spread. We find support for the hockey stick relation with bank’s stake in covenant-lite loans averaging 8% (0% median). We also find that covenant-lite loans are more likely when borrower moral hazard is less severe and when bank relationship rents are high.

Commonly used Jones-type discretionary accrual models applied in quarterly settings do not adequately control for nondiscretionary accruals that naturally occur due to firm growth. We show that the relation between quarterly accruals and backward-looking sales growth (measured over a rolling four-quarter window) and forward-looking firm growth (market-to-book ratio) is non-linear. Failure to control for the effects of firm growth and performance on innate accruals leads to excessive Type I error rates in tests of earnings management. We propose simple refinements to Jones-type models that deal with non-linear growth and performance effects and show that the expanded models are well-specified and exhibit high power in quarterly settings where one is testing for earnings management. The expanded models are able to identify the presence of earnings management in a sample of restatement firms. Our findings have important implications for the use of discretionary accrual models in earnings management research.
