Using a unique set of banking data containing both originally reported and subsequently revised financial variables, we study the incidence of adverse revisions to accounting statements. As might be expected, our findings indicate banks are more likely to underreport financial losses when their financial performance is substandard. In addition, we provide evidence that supervisory exams have an important role in uncovering financial problems and ensuring bank accounting statements reflect them. Specifically, our estimations point to a significant auditing effect, through which exams can lead to a restatement of financial results to reflect a greater degree of financial difficulty than originally reported. Interestingly, this auditing role of exams is evident not only for institutions previously identified as supervisory concerns, but also at highly rated banks, where financial problems are only just emerging. Because a banking downturn would increase not only the number of problem institutions requiring additional supervisory attention, but also the incidence of loss underreporting at highly rated banks, our findings stress the value of efforts to maintain or bolster the supervisory system's capacity to expand exam activity quickly and substantially.

A significant percentage of individuals with motion sickness demonstrate abnormalities in their time constant or vestibulo-spinal reflex function. These abnormalities can be detected using standard, land-based vestibular tests. These preliminary results have implications in understanding the etiology of motion sickness and may provide outcome measures to be used in treating motion sickness.

Each quarter, banks file a call report, or Report of Condition and Income, containing hundreds of accounting items pertaining to their financial condition. Because call reports are filed quarterly, whereas banks are typically examined about once every twelve to eighteen months, statistical early warning models using call report data potentially provide a more up-todate picture of a bank's condition than on-site exams alone. Often neglected, however, is the fact that call report data are subject to revision. We find evidence of a strong relationship between on-site exams and call report revisions. In addition, we evaluate a major class of early warning models using both originally published and revised data to assess whether model accuracy in real time is appreciably lower than accuracy measured using revised data. The findings indicate revised data overstate the accuracy of early warning models. The substantial effect of revisions on the accuracy of early warning models, coupled with the finding of a relationship between revisions and exams, points to a substantial auditing role for on-site exams. More generally, our findings point to the need for care in the use of call report data for research in which the real-time flow of financial information is of some concern.
