We investigate whether consistent non-GAAP reporting is associated with investment efficiency. Prior research finds a positive association between non-GAAP reporting and investment levels, concluding that it represents overinvestment. We corroborate this positive association, but additional tests are not consistent with the conclusion of inefficient overinvestment. Specifically, we explore the relation between investment and future cash flows as a proxy for the realization of investments in positive net present value projects. We find that the investments of firms that consistently report non-GAAP metrics are associated with similar or higher future cash flows than the investments of firms reporting only GAAP earnings, which is consistent with efficient investment. We observe similar associations in multiple specifications, performance horizons, and outcome variables, including future returns and earnings. Given the prevalence of non-GAAP reporting and the SEC's ongoing concern with the consequences of non-GAAP disclosure, our analyses offer timely evidence relevant to this important discussion.

We provide evidence that accruals quality in the U.S. has generally improved since 2000, following a decade of decline during the 1990s. Our results indicate that both the initial decline in accruals quality and the subsequent reversal can be explained by an inverse relation with operating cash flow volatility. Moreover, even though patterns of cash flow volatility and accruals quality vary in different regions of the world and relative to the U.S., we find evidence of an inverse relation between accruals quality and cash flow volatility globally. We corroborate our main results in a battery of additional tests, which also indicate that our results are not attributable to other explanations. Overall, our evidence challenges conventional wisdom and suggests that concerns about a sustained decline in accruals quality over time are unwarranted.
